Sáttítla Highlands National Monument

California

Managed by U.S. Forest Service, Pacific Southwest Region

Established 2025

224,676 acres

Website: https://www.fs.usda.gov/visit/national-monuments/sattitla-highlands-national-monument

Overview

In the northeast corner of California is the largest shield volcano in North America: 7,921-foot Medicine Lake Volcano. Sáttítla Highlands National Monument is spread across Klamath, Shasta, and Modoc National Forests just south of Lava Beds National Monument and features numerous cinder cones and lava fields. Part of the Volcanic Legacy Scenic Byway loops around Medicine Lake, which the Modoc people view as a place of healing. The Pit River Tribe opposed development of geothermal energy sources in this area, spearheading its protection. In the 1960s, NASA astronauts trained at Pumice Crater, four of whom eventually landed on the moon. Sáttítla Highlands National Monument is also important for biodiversity, providing habitat for wildlife species like the Cascades frog, long-toed salamander, and gray-headed pika, as well as numerous fungi, the parasitic sugarstick plant, and Pacific fuzzwort (a rare liverwort).

Highlights

Medicine Lake Recreation Area, Giant Crater lava tube, Glass Mountain, Black Lava Butte, Fourmile Hill Tree Molds Geologic Area

Must-Do Activity

Most of the developed recreation opportunities surround Medicine Lake, which offers boat ramps, trails, and campgrounds. Giant Crater has the longest known lava tube system in the world at 18 miles, although it is partially collapsed. This Geologic Special Interest Area can be accessed two miles off Medicine Lake Road on Forest Road 43N11. Another unpaved road leads up Glass Mountain, which has a crater full of sharp pieces of rhyolite obsidian and glossy dacite. This remote corner of California has some of the darkest skies in the continental U.S., so it is great for stargazing on moonless nights. In the winter, snowmobiling and cross-country skiing are popular activities on groomed trails.

Best Trail

There is a 4.4-mile loop around Medicine Lake, as well as the one-mile out-and-back Medicine Lake Glass Flow Trail that gains 68 feet of elevation on the north shore. For a more challenging route, Little Mt. Hoffman Trail gains 666 feet over three miles to the fire lookout, which can be rented overnight. Summitting the actual Mt. Hoffman is over 13 miles roundtrip with a 2,000-foot cumulative climb.

Photographic Opportunity

Sáttítla literally translates as “obsidian place” and the volcanic glass prevalent at Glass Mountain has provided humans sharp blades for at least 5,000 years.

Peak Season

Summer

Fees

$5 per vehicle (or the America the Beautiful Pass) at Medicine Lake

Road Conditions

Camping

There are multiple Forest Service campgrounds on Medicine Lake, plus two nearby at Blanche Lake and Bullseye Lake. Dirt roads in Modoc, Shasta, and Klamath National Forests have ample dispersed camping opportunities.

Modoc National Forest

April 15, 2026 Raven About The Parks 9 Comments

Modoc National Forest

California

Managed by U.S. Forest Service, Pacific Southwest Region

1,979,327 acres (1,663,401 federal/ 315,926 other)

Website: https://www.fs.usda.gov/r05/modoc

Overview

In the northeast corner of California, Modoc National Forest contains the largest shield volcano in North America: 7,921-foot Medicine Lake Volcano. This region has a long history of volcanism, as seen at Pumice Stone Mountain, Burnt Lava Flow, High Hole Crater, Hot Spot, and Glass Mountain (composed of rhyolite obsidian and glossy dacite). The basalt-topped plateau of Devil’s Garden is home to an 800-acre stand of western juniper. East of Goose Lake, the Warner Mountains rise from 4,300 feet to 9,892-foot Eagle Peak, and are covered by a mixed conifer forest of lodgepole pine, whitebark pine, ponderosa pine, incense-cedar, and red fir.

Highlights

Sáttítla Highlands National Monument, Volcanic Legacy Scenic Byway, Medicine Lake Recreation Area, Glass Mountain, Devil’s Garden Natural Area, Mill Creek Falls, Highgrade National Recreation Trail, Pine Creek Trail

Must-Do Activity

Medicine Lake offers boat ramps, trails, and campgrounds and nearby is Giant Crater, which has the longest known lava tube system in the world at 18 miles (although it is partially collapsed). Located up a dirt road often blocked by snowdrifts late into the summer, Glass Mountain has a crater full of sharp pieces of rhyolite obsidian and glossy dacite. This remote corner of California has some of the darkest skies in the continental U.S., so it is great for stargazing on moonless nights. In the winter, snowmobiling and cross-country skiing are popular activities on groomed trails. The South Warner Mountain Wilderness is traversed by the 21-mile Summit Trail that passes Eagle Peak, the Devil’s Knob, and The Slide. Mill Creek Falls is also in the Warner Mountains, accessed by a 3.4-mile out-and-back trail.

Best Trail

In the Warner Mountains near the border with Oregon’s Fremont National Forest, the 5.5-mile one-way Highgrade National Recreation Trail provides excellent views of Goose Lake. The trailhead is reached by taking paved County Road 9 five miles east from Highway 395 then turning north on the steep and unpaved Del Pratt Spring Road (Forest Road 47N72) for 6.3 miles. The trail quickly leaves the shade of the forest as it steadily climbs 800 feet through a slope covered in woolly mule’s ears flowers to a saddle west of 8,224-foot Mt. Vida. It is possible to summit Mt. Vida from this point, but the trail heads away toward Yellow Mountain following Forest Road 48N10.

Watchable Wildlife

Modoc National Forest borders Lower Klamath National Wildlife Refuge, in addition to Tule Lake, Clear Lake, and Modoc National Wildlife Refuges. These wetlands provide habitat crucial for bird nesting and migration on the Pacific Flyway. The many lava tubes provide habitat for numerous species of bats, in addition to violet-green swallows and bushy-tailed woodrats. Larger mammals include mule deer, pronghorn, badger, skunk, raccoon, pika, jackrabbit, yellow-bellied marmot, coyote, bobcat, and mountain lion. Large birds found here are great horned owl, short-eared owl, and bald eagle (winter resident). Reptiles are abundant, including the western fence lizard, northern sagebrush lizard, western skink, Rocky Mountain rubber boa, gopher snake, desert night, and western rattlesnake.

Photographic Opportunity

Not far up the steep Highgrade National Recreation Trail there are excellent views of Goose Lake to the west.

Peak Season

Summer

Fees

$5 per vehicle (or the America the Beautiful Pass) at Medicine Lake

Road Conditions

This area receives abundant winter snowfall, and roads can be blocked by snow into July, which we experienced trying to get to Glass Mountain. The road to Medicine Lake is paved, but almost every other road through the National Monument is unpaved, some requiring a high-clearance vehicle. Giant Crater is a Geologic Special Interest Area that can be accessed two miles off Medicine Lake Road on Forest Road 43N11.

Camping

There are multiple Forest Service campgrounds on Medicine Lake, plus two nearby at Blanche Lake and Bullseye Lake. Dirt roads in Modoc National Forest provide ample dispersed campsites.

Arizona, Update

Arizona Trail Days 14 to 23

March 30, 2026 Raven About The Parks 5 Comments

With temperatures 28 degrees above average in the Sonoran Desert, I jumped ahead 200 miles on the Arizona Trail to my home in Pine at Mile 459. After two “zero days” I was able to quickly cover the higher elevation miles and made it back to where I started on the South Rim of the Grand Canyon at Mile 700. The final six days I backpacked 187 miles, which I did not think I was capable of before I started on the AZT. This was all at elevations above 6,000 feet with the last 100 miles including water carries of 22, 17, 18, and 21 miles between refills. It was great to see friends and family in Pine and Flagstaff. I have surpassed 500 miles on the 800-mile AZT and will now return to the section I skipped north of the Gila River. Good news is the National Park Service is planning to reopen the North Kaibab Trail on May 15, so if I wait I may be able to do the final 100 miles through the Grand Canyon and up to the Utah border.

Arizona Trail Day 16, Mile 459 to 483 after jumping ahead 200 miles to my home in Pine I picked up the Highline Trail to the top of the Mogollon Rim. Enjoyed the cooler temperatures and the first Arizona cypress trees along the route, plus I saw a Madrean alligator lizard.

Arizona Trail Day 17, Mile 483 to 498 atop the Mogollon Rim across Clear Creek. Finished before noon for a trailhead pickup by my parents and one more night at home in Pine. Enjoying the cooler temperatures as I head towards Flagstaff through Coconino National Forest.

Arizona Trail Day 18, Mile 498 to 529 through forests towards Mormon Lake. Saw 3 herds of elk and the first Abert’s squirrel with its tassel ears. Water was mostly filtered from cattle tanks in various tints of yellow, but it tasted okay.

Arizona Trail Day 19, Mile 529 to 561 across Anderson Mesa where I saw two groups of mule deer. I got a resupply from my parents and my first views of the San Francisco Peaks north of Flagstaff. I feel nostalgic walking towards the town where I earned my undergrad degree from Northern Arizona University.

Arizona Trail Day 20, Mile 561 to 568 plus 16 miles on the urban route shortcut then Mile 599 to 608 through my college home of Flagstaff. Thanks to my friend Robin for helping lighten my backpack load earlier, picking me up near Snowbowl, and hosting me after a long 32-mile day.

Arizona Trail Day 21, Mile 608 to 638 dropped down from Aspen Corner on Snowbowl Road onto Hart Prairie. Saw mule deer, pronghorns, and corkbark fir, one of my favorite tree species. Passed scenic Red Mountain on my way to a dry camp in the pinyon juniper woodland.

Arizona Trail Day 22, Mile 638 to 668 through Babbitt Ranch and into Kaibab National Forest and the new Ancestral Footprints of the Grand Canyon National Monument. Not many water sources out here so you take what you can get.

Arizona Trail Day 23, Mile 668 to 700 past Grandview Tower to Tusayan for fast food and then into Grand Canyon National Park where I started on March 4th. At some point today I surpassed 500 miles on the 800-mile AZT. I also had my first hotel stay of the journey. I’m taking a zero day before heading back to the Gila River at Mile 265.

Update

Starting the Arizona Trail This Week!

March 2, 2026 Raven About The Parks 8 Comments

This week I am starting out northbound on the Arizona National Scenic Trail. According to the official website, it is 800 miles (with 105,000 feet of cumulative elevation gain) from the international border with Mexico in Coronado National Memorial to the Stateline Campground on the Utah border in Vermilion Cliffs National Monument. Due to last summer’s Dragon Bravo Fire in Grand Canyon National Park, more than 20 miles of the trail is closed on the North Rim making a thru-hike impossible this year. Since I am already in northern Arizona, I am going to begin by backpacking to the bottom of the Grand Canyon to spend one night before turning around and driving south to the official start. That will be on Wednesday! Once I return to Grand Canyon National Park (Mile 700), I will get a ride north to finish up the trail.

I recently moved back to Arizona for the 5th time in my life and I thought backpacking across the state would be a great way to reconnect. If you haven’t already read it, check out my 7-day Arizona Road Trip Itinerary with plenty of options to make it a month-long visit.

Once I finish the Arizona Trail, then I will get back to writing my latest guidebook American History 101: Reliving a Country’s Past at 101 National Park Service Sites, which I hope to publish by July 4, 2026, for the 250th anniversary of the vote to approve the Declaration of Independence.

Mendocino National Forest

February 11, 2026 Raven About The Parks 4 Comments

Mendocino National Forest

California

Managed by U.S. Forest Service, Pacific Southwest Region

1,079,850 acres (911,733 federal/ 168,117 other)

Website: https://www.fs.usda.gov/r05/mendocino

Overview

Originally called California National Forest in 1908, this area between Interstate 5 and Highway 101 was renamed Mendocino National Forest 24 years later. It stretches north-south along the Coast Range covering parts of six counties north of San Francisco. Similar to Los Padres National Forest, it contains rocky serpentine ridgelines where only specially adapted plants can tolerate the heavy metals in the soil, like Sargent cypress and the shorter McNab cypress. Both species can be found along Frenzel Creek near Little Stoney Campground. In 1953, a Forest Service employee and 14 volunteer firefighters died in the Rattlesnake Fire and a memorial overlooking Rattlesnake Canyon is located off Forest Highway 7 on Alder Springs Road. Mendocino National Forest includes the northern portion of Berryessa Snow Mountain National Monument (see our full blog post), established in 2015 and administered in cooperation with the Bureau of Land Management.

Highlights

Berryessa Snow Mountain National Monument, Lake Pillsbury, Thomes Gorge, Hull Mountain, Frenzel Creek, Harvey Peak, Ide’s Cove Trail

Must-Do Activity

There are 18 National Forests in California (the most of any state), but Mendocino is the only one not crossed by a paved highway. It is a wonderful destination for outdoor recreation, both motorized and non-motorized, including Hull Mountain which is popular with hang gliders. Lake Pillsbury is 2,280 acres and offers boat ramps, campgrounds, and a resort, while 35-acre Letts Lake has a campground and access to hiking trails.

Best Trail

As we drove the winding road from Stonyford to the tiny roadside pullout for Deafy Glade Trail, we passed campgrounds full of RVs that were getting ready for a motorcycle event. Our hike took us far from any road noise, as we dropped down to and waded across the frigid South Fork of Stony Creek and then climbed steeply to 5,300 feet in elevation. The trail continued to the summit of 7,056-foot Snow Mountain, but we already had great views of the Rice Valley and decided to turn around at the 4.5-mile point, just inside the official boundary of the Snow Mountain Wilderness. We expected a desolate landscape after reading about recent fires, but about three-quarters of the trees along the trail were still alive and showed only minor charring at their bases.

Watchable Wildlife

Mendocino National Forest protects a biodiverse area home to tule elk, black-tailed deer, river otters, black bears, and mountain lions. Rivers that drain these highlands are used by California coastal chinook salmon and Northern California steelhead. Fishing in the lakes is a popular activity and a chance to see ospreys and bald eagles.

Photographic Opportunity

On Deafy Glade Trail, there were congregations of lady bugs that numbered in the hundreds along the South Fork of Stony Creek.

Peak Season

Summer

Fees

None

Road Conditions

Fouts Springs Road (Forest Road M10) is a well-maintained gravel road that crosses the National Forest west of Stonyford. That area is popular with motorcycles and OHVs, so keep an eye out for them while driving.

Camping

Mendocino National Forest manages Bear Creek Campground and Lower Nye Dispersed Campground among many others, plus there are countless places for dispersed camping.
