Wind River Range, Wyoming
August 1, 2023-August 10, 2023

This program is designed for adventurers who are outdoor enthusiasts and are interested in backpacking adventures, fly fishing and field studies in the Rocky Mountain wilderness.

Expedition Overview

Excursion Description

The nature of this excursion is the study of unique western ecosystems by total immersion in those systems. This is done by backpacking into a wilderness area, taking only what you can carry on your back, and subjugating yourself to the wilderness condition by experiencing it in a minimal-impact, educational fashion. The trip is physically strenuous, very rigorous and at high altitudes. You must be able to withstand the physical and emotional rigors of 7 nights tent camping with 5 days of that in the backcountry in primitive, wilderness conditions. Participants must be physically able to withstand the rigors of such a trip.

The Wind River Range is located in north central Wyoming southeast of Grand Teton National Park, west of the towns of Lander and Pinedale and east of Dubois, Wyoming. We will be mostly in the Popo Agie Wilderness Area located within the Shoshone National Forest. It is a high altitude range with an average elevation of ~10,000 feet. With respect to wilderness, it is one of the largest in the contiguous United States and is part of the Bridger, Shoshone and Popo Agie National Forests. It is a wilderness lovers’ paradise with vast roadless areas, large glacial lakes, massive rock formations, and flora and fauna unique to the central Rocky Mountain west. Continuing in a northwesterly direction, the mountains merge with the north-south trending Tetons on the other side of the Jackson Hole.

Pre-trip Orientations

Due to the high degree of preparedness required for this trip, we will plan on meeting with participants multiple times prior to departure to go over gear, packing, and physical preparations. These meetings can take place in-person or virtually and will be planned once we have a crew signed up to go.

Outdoor Component

Areas to be visited: Popo Agie Wilderness Area, Shoshone National Forest, Wind River Range, Wyoming

Backpacking: backpacking is the basic component of this course; being able to carry only what you need for an extended trip (8 days) into the wilderness is essential to maintain the roadless, natural qualities of an area

Fly fishing: with its large lakes and clear streams, the Wind River Range offers some of the best mountain fly fishing to be experienced in Wyoming. There will be plenty of opportunity to fish at our backcountry basecamp.

Natural history of the Wind River Range: including geology, wildlife, and unique alpine plant communities (we might see or hear a mountain lion or wolf here too)
