About this map

Chicago Basin serves as a central hub within this high-elevation landscape of the San Juan National Forest, where steep ridgelines and glacial basins define the topography. The map illustrates a complex network of established routes, including the Needle Creek Trail 504 and Vallecito Trail 529, which provide access to remote alpine lakes such as Columbine Lake and Castilleja Lake. Notable peaks like Windom Peak and Mount Eolus overlook the Crystal Valley, highlighting the extreme vertical relief of the Needle Mountains.

Water management and natural hydrology are prominent features, with the City Reservoir and its associated City Reservoir Trail 542 located near West Silver Mesa. The drainage patterns of the Florida River and Vallecito Creek carve through the terrain, passing landmarks like Soda Spring and Upper Park. This 2013 survey provides a clear look at the trail systems and geographic markers essential for navigating this portion of La Plata County.
