Chasm Meadow is a lovely spot up towards Chasm Lake from the Chasm Junction intersection on the Longs Peak climb.  Joe Arnold had designed and constructed solar evaporating toilets in the previous decades and these were totally overwhelmed by increasing usage.  This (and the other Longs toilets) designed were based around the urine diverting BTW seat, and custom designed by CU Denver students to blend in with the Wilderness surroundings using gabian basket construction.  Waste is collected in small Mini Waste Away bags in a rear steel compartment.  Waste is periodically removed by pack llamas.
