Figure 8. A 2008 view of Palmer Hill Delta foreset beds exposed in the Crooker Pit. This exposure is near the terminus of the northernmost meltwater channel shown on the map. The delta top apparently was washed by ocean waves in this area, forming the well-stratified pebble gravel on top of the foreset beds. This horizontal gravel unit resembles topset beds, but is finer-grained and slightly lower than the actual topsets.
