Garden of the Gods at Colorado Springs: Paleozoic and Mesozoic Sedimentation and Tectonics

Primary Leader: Timothy L. Clarey
Leader(s): John H. Whitmore, Marcus R. Ross, William A. Hoesch, Steven A. Austin
Field Trip Description: Participants in this eight-hour field trip will visit five sites along the Rampart Range and Ute Pass fault zones west of Colorado Springs, Colorado. The purpose is to observe and discuss the processes of sedimentation and tectonics at superb exposures near the Garden of the Gods. Only short hikes will be made from the vehicles. Five sites are to be visited: (1) a nonconformity below Cambrian strata at the base of the Sauk Sequence; (3) coarse clastic sedimentation in the late Paleozoic Fountain Formation; (3) marine sandstones and shales as evidence of the Cretaceous Western Interior Seaway; (4) clastic dikes (sand “injectites”) within the fault hanging wall; and (5) upturned strata at Garden of the Gods in association with Laramide tectonics on the Rampart Range fault.
Field Trip will span: 1 day
Sponsor(s): GSA Sedimentary Geology Division
