If you’re looking to pick up some famous trail signs, Aspen Snowmass is currently running an auction until Sunday. The proceeds raised, which is over $23,000 so far, will go towards the Aspen Skiing Company’s nonprofit Environment Foundation, which supports “regional environmental organizations.” Signs are from the four mountains, and also feature signs for various lifts and restaurants. The auction closes on Sunday at 7 pm Mountain Time. You can view the auction here. Please note that you’ll have to pick up the trail signs in person. Image Credits: Aspen Snowmass
