initial set-up. Two installations were also established at the Crescent Creek survey area. Four cameras remain on
the landscape; three from the 2015 season (one at Grizzly Creek and two at Green Lakes), and one from the 2016
season (Blum Lakes). No photos have been received from these four cameras, though we are planning retrieval
missions this spring or summer as locations become accessible. These survey areas are in remote, relatively high
elevation locations in the North Cascades, most requiring hours of off-trail navigation and bush-whacking to
reach. The challenge that these site locations have posed to our volunteers are cause for reflection and potential
adjustments in our upcoming 2017 monitoring season.
