The Pajarito Plateau, where Los Alamos is situated, features ash and lava flows carved by runoff from the Jemez Mountains, creating a series of long, thin mesas separated by canyons. This environment provides diverse terrain, ranging from ponderosa pine stands to areas with basalt, tuff, and loose gravel surfaces. The region's extensive trail network includes forest roads and doubletrack suitable for no traffic gravel bike trails.

The Valles Caldera, a twenty kilometer wide circular depression, is a geological gem created by a volcanic eruption that took place around 1.25 million years ago. Today it is a protected area that covers over 39,000 hectares and attracts around 120,000 annual visitors who wish to hike, horseback ride, mountain bike, camp or fish for trout, as well as cross-country skiing and snowshoeing in winter. Located just 22 kilometers west of downtown Los Alamos, the Valles Caldera National Preserve is also a popular hunting destination, as it claims the second largest elk population in the state, and more 400 wild turkeys live in the reserve from April to December. Other wildlife, such as prairie dogs, black bears, and golden eagles, also call this wilderness home.

Valles Caldera (or Jemez Caldera) is a 13.7-mile (22.0 km) wide volcanic caldera in the Jemez Mountains of northern New Mexico created by spectacular volcanic eruption of the Southwest's supervolcano about 1.25 million years ago. Hot springs, streams, fumaroles, natural gas seeps and volcanic domes dot the caldera floor landscape. The highest point in the caldera is Redondo Peak, an 11,253-foot (3,430 m) resurgent lava dome located entirely within the caldera. Also within the caldera are several grass valleys [Valle(s)] the largest of which is Valle Grande, the only one accessible by a paved road. Much of the caldera is within the Valles Caldera National Preserve, a unit of the National Park System. The preserve is known for its huge mountain meadows, abundant wildlife, and meandering streams. https://en.m.wikipedia.org/wiki/Valles_Caldera http://www.nps.gov/vall/index.htm
