This report summarizes snow-tracking efforts for the winter of 2017- 2018. This field season was the twelfth winter of snow-tracking along Interstate 90, east of Snoqualmie Pass. This winter was marked by a consistently good snowpack that lasted through March allowing transects to be completed from late December to mid-March. With the permanent addition of a transect west of Snoqualmie Pass and our second season of off-highway American marten track surveys, the project completed one of its busiest field seasons on record. Project Overview CWMP is a joint project led by Conservation Northwest and the Wilderness Awareness School. The program utilizes remote cameras year-round to document rare and sensitive species throughout core areas in the Cascades, as well as for more common species in strategically important locations. During the winter months, trained CWMP volunteers use snow tracking to monitor the presence, location, and movement of wildlife near proposed wildlife crossing sites east of Snoqualmie Pass along Interstate 90 in the Washington Cascades. Since its inception, CWMP has remained an asset to wildlife agencies and
