232 REPORT UNITED STATES GEOLOGICAL SURVEY. 



yellowish-gray color, and although its stratification is regular, it seems 

 to have undergone some degree of metamoi phisin. 



From Provo Valley our journey was by the wagon-road to Salt Lake 

 City. At the museum in the city Mr. Barfoot showed me some fossils 

 that had been collected at different places in the Territory, among which 

 I recognized some of the species, specimens of which were brought from 

 Upper Kanab, Southern Utah, by Professor Powell, whence these also 

 are reported to have come. After renewing my outfit at Salt Lake City 

 I turned eastward, going by way of Parley's Park, to Coalville, on Weber 

 Elver, where a large series of fossiliferous Cretaceous strata is exposed. 



In the An. Eep. U. S. Geol. Sur. Terr, for 1872, p. 439, Mr. Meek gives, 

 as the result of his investigations in Weber Valley, a detailed section of 

 the strata exposed there, from the vicinity of Coalville to Echo Cafion. 

 This section was found to represent, with sufficient accuracy, the Creta- 

 ceous strata of that vicinity, except that there seems to be in it, near the 

 southeastern end, some duplication of strata, doubtless caused by the. 

 presence of a fault there. This, however, does not seriously impair the 

 usefulness of the section. About 3,000 feet in thickness of these strata 

 are fossiliferous, many of them profusely so. The following list com- 

 prises only those that have been found within the compass of this section, 

 in the neighborhood of Coalville. 



The greater part of the species of the following list were published by 

 the late Mr. Meek in the Am. Eep. U. S. Geol. Sur. Terr, for 1872, and 

 vol. iv U. S. Geol. Sur. 40th Parallel. Other publications of a part of 

 them were made by myself in vol. iv U. S. Sur. & Expl. West of 100th 

 Meridian, Powell's Eeport on Geol. Uinta Mts., and in another part of 

 the present volume.
