17 Aug, Sunday
0830 – Vehicles depart for Minnie’s Gap on Wyoming/Utah border (1 hr drive). We will
examine steep deltaic clinoforms (20-40 m in height) impacted by river-wave interaction and
with incised valleys in Chimney Rock. Time permitting, we will also visit more gently dipping
clinoforms in the overlying Brooks Sandstone. Both are Campanian. About 5 km of walking is
involved, but mainly on trails. We’ll return to Rock Springs about 1800.
18 Aug, Monday
0830 – Vehicles depart for Rawlins (1.5 hr drive). We will examine shelf-margin deltas with
fluvial and tidal processes on their front. An overlying valley contains sandy river deposits that
become highly deformed toward the shelf edge. Subsurface data indicate that the valley
connects with a deep-water turbidite slope and two large deep-water fans. Subsurface data along
strike show that where the shelf edge was wave dominated, there are muddy slopes and no downdip fans. We’ll return to Rock Springs about 1830.
19 Aug, Tuesday
Throughout morning – Shuttles depart for Salt Lake City
