It is prominent as seen from Los Alamos and communities along the Rio Grande in northern New Mexico, but is relatively inconspicuous from Santa Fe, as its north-south trending main ridge line is seen nearly end-on, disguising the size of the mountain.

Tree line in the Sangre de Cristos is unusually high (exceeding 12,000 feet (3,700 m) in places) and only the top 600 to 800 feet (180 to 240 m) of the mountain is perpetually free of trees, but several severe forest fires have created bare spots extending to lower elevations.

An extensive region of aspen trees on its flanks produces spectacular orange-yellow coloration during the fall that is the subject of many photographic studies.

The attribution of the name to J. Robert Oppenheimer may be influenced by his known connection to Katherine Chaves Page Kavanaugh, as he was a frequent guest at the Ranch.

Under good conditions the summit is a simple "walk-up" climb, but the Sangre de Cristos are unusually prone to lightning, and during the summer months, the wise hiker is off Santa Fe Baldy and other high summits in the range by noon, to avoid afternoon thunderstorms.
