Fig. 22.27. Generalized cross sections of the Muddy Mountain thrust (upper diagram) and 

 Wheeler Pass-Johnnie thrust (lower diagram). In the upper diagram, section 22 of Fig. 22.1, 

 the Paleozoic strata are limestone and dolomite, and the Jurassic strata are thick-bedded sand- 

 stone. In the lower diagram about 21,000 feet of strata are shown in the thrust sheet, but 8000

more of younger strata were probably affected by the thrust. The Johnnie and Wheeler Pass 

 area is 60 to 80 miles west of the Muddy Mountains, section 23 of Fig. 22.1. Both diagrams after 

 Longwell, 1945.
