recognized on the soft slopes of the Traverse Mountains, was determined by 

 barometrical measurement to be 870 feet above the level of Salt Lake. 



The Pelican Hills constitute a low, flat-topped ridge which borders Utah 

 Lake on the west, made up of thinly-bedded gray and blue limestones, with 

 intercalated lighter-colored arenaceous beds and quartzites, closely resem- 

 bling those which form the summit of Timpanogos Peak, to which the few 

 fossil remains obtained from them, consisting chiefly of Spirifers and Crinoid 

 stems, also ally them. They probably represent the upper members of the 

 Lower Coal-Measure group. The strata are nearly horizontal; on the east- 

 ern slopes of the ridge having a slight inclination to the westward ; while 

 on the west side they dip nearly 10° to the eastward, showing a slight 

 synclinal fold. This easterly dip is continued in the southern portion 

 of the hills, beyond the limits of the map. From the comparatively 

 horizontal position of the strata, it would seem that this mass must have 

 been faulted up.
