Camp Muir is the campground on the 10,000-foot level of Mount Rainier used as a base camp by about two-thirds of the climbers going for the 14,411-foot summit.

It consists of an A-frame storage structure, a so-called “black box” shelter that can sleep 36 people and four toilets.

The News Tribune reports the park wants to make $700,000 in improvements, especially to the toilets. The park uses a helicopter to fly about 2 tons of human waste off the mountain each climbing season.

The park is holding hearings on options Monday in Ashford and Thursday in Tacoma. Work at Camp Muir could start next summer.
