The Role of Evaporation Dissolution
A net-salt isopach map of the Hutchinson Salt Member (Watney and Paul, 1980) shows that the Hutchinson-Yaggy study area (green box) lies within 10 miles of the main salt-dissolution front (closely spaced contours). The axis of the Voshell Anticline, a prominent faulted anticline affecting Paleozoic strata and believed to be related to north-northeast-trending salt dissolution, is shown. A local, northwest trend in the salt-dissolution front between Hutchinson and Wichita coincides with the course of the Arkansas River, which continues along this linear trend for 50 miles to the northwest.
