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 down-dip fans. We’ll return to Rock Springs about 1830.
19 Aug, Tuesday
Throughout morning – Shuttles depart for Salt Lake City
