Bear Creek has been noted in most catalogues as having been 

 found in Denver County^ Colorado, also a mistake, as Colorado has 

 no county by this name. It was first mentioned by Shepard* as found 

 upon the eastern slope of the Sierra Madre Range of the Rocky 

 Mountains. Again Henryf notes it as found in a deep gulch near 

 Bear Creek, about 25 or 30 miles from Denver. Smith;}; in describ- 

 ing this meteorite gave it the name of Bear Creek. As Denver is on 

 the boundary line between Arapahoe and Jefferson counties, and as 

 there is a Bear Greek extending clear across Jefferson county from 

 west to east, emptying into the Platte, according to Henry's descrip- 

 tion, this would bring the locality of the Bear Creek meteorite in the 

 western central part of Jefferson county. Therefore, it seems likely 

 that the iron noted in the Shepard Collection as "Jefferson, 30 miles 

 from Denver," is in reality a portion of the Bear Creek meteorite 

 labelled " Jefferson," meaning Jefferson county, and that the date of 

 fall, June, 1867, is an error. Particularly so as the Bear Creek is 

 described by Henryf as being " shattered on one end," so that small 

 pieces could be readily detached. 



Denver county has evidently been substituted for Denver city 

 in many of the meteorite lists, as no county is given in any of the 

 early reports of the Bear Creek meteorite. Moreover, the Sierre 

 Madre Range is west of Denver, and Bear Creek is described as hav- 

 ing been found on its eastern slope, which, in all probability, would 

 bring it in Jefferson county. So it would seem best that ' ' Jefferson 

 should be discarded entirely as a distinct fall and be called Bear 

 Creek, and that Denver county in all meteorite lists should read Den- 

 ver city. Thus we reduce the Colorado meteorites to four distinct 

 falls.
