Hager Mountain is a volcanic peak in Oregon in the northwest corner of the Basin and Range Province in the United States. The mountain is located south of the small unincorporated community of Silver Lake in south-central Oregon, and it is in the Fremont–Winema National Forest. On the summit, there is a fire lookout operated during the summer and fall by the United States Forest Service. There are several hiking trails that lead to the lookout station.
Geography and geology
Hager Mountain is located on the edge of Oregon's high desert in the northwest corner of the Basin and Range Province of the western United States. The mountain is in Lake County, approximately 10 miles (16 km) south of the small unincorporated community of Silver Lake. The summit of Hager Mountain is at 7,189 feet (2,191 m). The mountain's topographic prominence is 1,455 feet (443 m).[2]
Hager Mountain is a large siliciclava dome structure that was formed approximately 5.9 million years ago. The mountain's primary rock is from the Hayes Butte Basalt flows. The eruptions that produced these flows came from a fault zone running southeast–northwest between Hager Mountain and Hayes Butte. The eruptions that created Hager Mountain released lava that flowed down the slopes of the volcanic dome onto plains around the mountain. The Hayes Butte Basalt overlays the Fort Rock Formation and earlier Picture Rock Basalt layers. All of these lava flows occurred during the Pliocene epoch. The Hayes Butte Basalt flows that form Hager occurred near the end of that epoch.[4][5][6][7]
When exposed on the surface, Hayes Butte Basalt generally weathers into a thin and rocky soil. Today, Hager Mountain's soil is a loose, unconsolidated mix of fine alluvial particles, gravel, and a variety of larger rock fragments. Common surface rocks include basalt, andesite, pumice, and obsidian.[6][8]
Environment and ecology
Hager Mountain lies east of the Cascade Range in the northwestern corner of North America's basin and range environment. To the west, ponderosa and lodgepole pine forest extends to the timberline on the Cascade peaks, approximately 50 miles (80 km) away. The areas north and east of the mountain are drier, typical high-desert country.[9][10]
The Klamath people of south-central Oregon called the mountain Chock-chock-lisk-se, meaning "bald faced rock." Some early maps of the area show the mountain as Bald Mountain. However, early settlers called it Hagerhorst Mountain, after a pioneer rancher who lived just north of the mountain in the Silver Lake Valley. Over the years, the name was shortened to Hager.[15][16]
The United States Forest Service built a fire lookout on Hager Mountain and began manning it full-time in 1915.[17][18] The original lookout was replaced with a new structure in 1954. The current lookout is a 14 feet (4.3 m) by 14 feet (4.3 m) one-room cabin with large glass windows on all four sides. From it, the forest guard has a 360 degree view of the surrounding landscape. The Forest Service mans the lookout from June through October each year. There is a dirt road leading to the summit. The road is used only by the lookout on duty; it is not open to the public.[11][16]
There are three day-hike trails that lead to the summit of Hager Mountain, in addition to the Fremont National Recreation Trail. The easiest trail is a 2-mile (3.2 km) roundtrip from the road gate on the west side of the mountain. It has an elevation gain of 785 feet (239 m) and is normally open from June through mid-November. The second trail is a little more challenging. The route covers 3.3 miles (5.3 km) each way. The trailhead is located on the northwest side of the mountain, just off Forest Road 012. This trail has an elevation gain of 1,710 feet (520 m). The longest trail is an 8-mile (12.9 km) roundtrip hike. The trailhead departs from Forest Road 28 near milepost 9 on the east side of the mountain. The elevation gain along this trail is 1,990 feet (610 m). The two longer trails merge about halfway to the summit and then link to the Fremont National Recreation Trail a short distance later. The Fremont trail leads to Fremont Point and Winter Rim, approximately 25 miles (40.2 km) southeast of the trail junction.[11][12][16][21]
From the lookout station on the summit of Hager Mountain, visitors have an excellent view of Cascade peaks to the west as well as the high-desert country of northern Lake County to the north and east. Visitors can see as far north as Mount Hood and as far south as Mount Shasta from Hager's summit.[9][11][12][16]
A Forest Service guard lives on-site at the Hager Mountain lookout during the summer wildfire season. However, the public is able to visit the lookout during this period. After the fire season is over, the lookout can be rented by the public for recreational purposes from November through May.[16] The lookout has a wood stove for heating the building, along with a propane cooking stove and a propane refrigerator. There is a single bed and three sleeping cots. Outside, there is a picnic table and an outhouse with a vault-type toilet. There is no drinking water at the site.[16][19][22][23]
