Certain springs near Hot Springs conform to and others are 

 above the mean annual temperature of the air at Hot Springs 

 which, based on the thirty-year record of the United States Weather 

 Bureau, is 60.5° F. To this temperature the water of "ordinary" 

 springs should closely approximate. Springs above the normal 

 temperature are probably common as shown by the table below :

GEOLOGIC SETTING OF THE HOT SPRINGS 



Most of the following discussion of the general geology of the 

 region is condensed from a paper by Miser^ and from the manu- 

 script of a geologic folio by Purdue and Miser,^ to be published by 

 the United States Geological Survey, The geologic map, Figure i, 

 is largely a redrawing of the map in this folio. The Hot Springs 

 are situated in that part of Arkansas known as the Ouachita Moun- 

 tains. These mountains are composed of numerous nearly east 

 to west ridges and several intermontane basins. Some of these 

 mountains are simple ridges, but others are small ranges. The
