This pass connects the East Eagle Valley with the Lakes Basin. This pass is technical in nature, but the trail is easy to follow and in fairly good condition. There is not much water between the start of the western climb and Upper Lake on the eastern side, so be sure to load up before you climb up and over.

A small cirque above Mirror Lake, Upper Lake offers a quiet spot for camping as well as a good water source for filtering below the Ivan Carper and Horton Passes.

Mirror Lake is one of the most popular destinations in the Wallowa Mountains, so don't be surprised when you find a lot of people camping along its shores. Most maps show a camping symbol on the northwest corner of the lake; this is where people will likely head to set up camp (it's where we went in the dark!). If you are willing to hike further to the east, you'll find some great locations (try crossing the creek on the east side - really great camps up on the granite!). Be sure to pitch your tent at least 100 feet from the lakes or wetlands - you will be asked to move by the rangers if you set up too close.

Right here, the beautiful Minam River flows into the Wallowa River and continues to shape the landscape. If you are lucky, you can watch some whitewater rafter passing.

Until I got here, I was convinced, the majestic Grand Canyon is the deepest canyon the United States. In fact, Hells Canyon, shaped by the Snake River, takes the cake. The overlook offers a nice panoramic view with some benches to spend more time. There is also a pit toilet available.
