About this map

Ross Dam serves as the focal point of this North Cascades landscape, holding back the expansive waters of Ross Lake. The settlement of Ross Lake Resort and the Ross Dam District Ranger Office sit along the northern reaches of the reservoir, while further south, the Skagit River connects to Diablo Lake. This 2011 survey documents the established recreational and administrative infrastructure of the region, including the Colonial Creek Campground and Diablo Vista.

The terrain is defined by dramatic elevation changes, from the depths of Thunder Arm and Ruby Arm to the heights of Ruby Mountain and Colonial Peak. Glacial features such as Neve Glacier feed into a complex drainage system including Thunder Creek and Neve Creek. For those interested in backcountry navigation, the map clearly identifies significant landmarks like John Pierce Waterfall, Fourth of July Pass, and the Ruby Creek Barn and Horse Pasture.
