The picturesque Sangre de Cristo range of southern Colorado / northern New Mexico is a magnet for outdoor enthusiasts of all types. I've personally been hiking, fishing, rock climbing and mountaineering in the range. It contains 8 of Colorado's coveted
14ers - that is, summits exceeding 14,000 feet in height. (Some consider Ellingwood Peak to be a subsidiary summit of Blanca Peak, leaving 7 14ers instead.) The northern - or
Crestone - section of the range contains four 14ers: Crestone Needle, Crestone Peak, Kit Carson Peak and Humboldt Peak. Here's an edWare3D rendering of this portion of the range, viewed from the west over a cloudy San Luis Valley:

To the south lies the Blanca Massif containing Blanca Peak, Ellingwood Peak, Mt Lindsey and Little Bear Peak. Here's a nice south-to-north fly-over of the range. After topping the Blanca Massif, look for Great Sand Dunes National Park to the west (left.)
Happy travels!
