Mt. Langley Summit Surveys
July 29 – August 4, 2026
This is a week of scientific survey work in the high Sierra of Sequoia National Park. Participants are National Parks and NPS and US Forest Service staff, volunteer botanists, students, research scientists and previous GLORIA survey attendees. This is a physically demanding GLORIA trip, where participants backpack to a backcountry camp with all their own food and gear. From our basecamp, we hike each day to survey the summits. There is a high likelihood that we will need to use our weather/make-up day, so we need participants to be available for the full survey dates. Please send us an email if you are interested in attending!

From downtown Lone Pine, take the Whitney Portal Road west into the mountains. After 3.1 miles, turn left on Horseshoe Meadows Rd. Take this for 19.4 miles and turn left into the campground. See the map below. The Cottonwood Pass trailhead campground is on Google Maps for easy navigation.
Camping
This survey requires a solid backpack in to our base camp at Upper Soldier Lake where we will camp for the duration of the survey. The night before the hike in, we will camp at the Cottonwood Lakes Walk-in campground. Participants are expected to supply all of their backpacking and camping gear although gear can be rounded up for those who may be missing an item.
