Denali's 2006 Backcountry Management Plan (BCMP) outlines indicators and standards to assess important Resource and Social Conditions related to wilderness character and the visitor experience. Monitoring in the 2017-2021 seasons will include ongoing field observations of informal trails and campsites, backcountry impacts (litter, encounters with modern equipment, aircraft noise dose, and water quality), as well as encounters with other groups while hiking and camping. Included in this monitoring effort is the use of trail counters and cameras to quantify and qualify use of both formal and informal trails.
