Detour to the San Juans

Returning to Littleton from Crested Butte, I opted for a detour to the south, covering a stretch of landscape between Gunnison and Creede that I had not previously explored.  Just west of Gunnison, at the east end of the Blue Mesa Reservoir, I turned south on Colorado 149, undulating across sage grasslands that are broken by rocky outcrops.

After dipping through a few creek valleys, the highway makes a significant descent to the Lake Fork of the Gunnison River which it follows upstream.  Hemmed in by cliffs of volcanic sediments, the river rises in the northern San Juans near Lake City.  After passing through that town, Route 149 begins a climb toward Slumgullion Summit, about 11,600 feet; en route, the road offered a spectacular view of Lake San Cristobal and, at the summit, a broad view of majestic peaks to the northwest.  Unfortunately, bark beetles have decimated the forest in this area (as in many other areas of the San Juans); dipping through pockets of dead and cleared forest, the highway crosses the Continental Divide at Spring Creek Pass (a thousand feet lower than Slumgullion Summit) and begins a winding descent toward the Rio Grand River.

Along the way, an overlook provides a magnificent view of the uppermost Rio Grand Valley, including the Rio Grande Reservoir and Pyramid Peak; the north flank of that mountain has been officially recognized as the source of the Rio Grande.  Paralleling the river just upstream from Creede, Route 149 winds eastward along the Rio Grande all the way to South Fork, Colorado, where it intersects US 160 and the river's southern fork.  Turning east on this highway, I headed toward the San Luis Valley and familiar landscape.
