STS100-708-12 Big Horn Mts., Wyoming. Collision (~60 m.y. ago): Pacific Ocean plate was driven under N. America, producing thrust-faulted and folded ranges from British Columbia southward into Mexico. Ancient basement rocks were brought up in block uplifts such as the Big Horn Mts.

STS100-711-66 Colorado Plateau, Grand Canyon, Lake Powell. At the same time that the folded and thrust-faulted Rocky Mts. were created, the Colorado Plateau was also uplifted. Carving of the Grand Canyon by the Colorado River was much later -- < 4 mybp.

STS100-704-147 Great Salt Lake occupies a basin of the Basin and Range. Bonneville salt flats (bright area around GSL) mark the extent of Ice Age (Pleistocene) Lake Bonneville. Bingham copper mine and tailings ponds are visible at south end of Salt Lake.

STS100-704-141 Coast Range. About 24 m.y. ago the Coast Range, consisting mainly of marine sedimentary rocks, was uplifted as the Pacific and N. American plates converged. The Central Valley, a foreland basin, formed at that time and the granite masses of the Sierra Nevada were emplaced. Transform fault movement along the margin began ~5 m.y. ago: The Pacific plate began moving more northward, and large-scale lateral movement began on the San Andreas fault zone.

STS100-704-144 Basin and Range province, Sa. Nevada, Mono Lake, Lake Tahoe. Relatively rapid, regional extension (~24 m.y. ago): The crust beneath the Basin and Range province was heated, softened and stretched--in some places as much as 150% -- producing basins and ranges bounded by low-angle faults.

STS100-704-152 Rio Grande rift from Albuquerque, NM to ~Van Horn, TX. Rifting (~24 m.y. ago): Long, comparatively simple string of fault-bounded valleys and flanking mountain ranges, such as the Sandia Mts. east of Albuquerque. The rift extends from at least North Park, CO to southern Coahuila, MX.

STS100-704-112 Rio Grande rift. From the Sacramento Mts. and White Sands, the Rio Grande rift continues southward into West Texas. The Guadalupe Mts. are a flanking uplift on the east side of Salt Basin rift valley (bright area near center).

STS100-709-62 Channel Islands, CA. Santa Rosa, Santa Cruz. Branches of the San Andreas fault system step westward north of Los Angeles; the two sides of the fault are converging, as well as moving laterally past each other. That interaction has resulted in local uplift, such as where the Channel Islands have been raised above sea level.

STS100-708-4 Cascade Range. At about the latitude of Mt. Shasta, CA (north of the San Andreas system), part of the Pacific plate is diving beneath North America. Inland from the subduction zone is the Cascade chain of active volcanoes, including Mt. Adams and Mt. St. Helens. The summit crater and channels of the mudflows (lahars) that followed the 1980 eruption are clearly visible here.
