On this day in Lewis & Clark history...

At Plum Camp near present Oacoma, Lewis attempts to collect a female pronghorn and is surprised by how fast they can run. Colter kills a new type of deer, later named a mule deer. Lewis describes the black-billed magpie and coyote.

this senery already rich pleasing and beatiful, was still farther hightened by immence herds of Buffaloe deer Elk and Antelopes which we saw in every direction feeding on the hills and plains. I do not think I exagerate when I estimate the number of Buffaloe which could be compreed at one view to amount to 3000.

we found the Antelope extreemly shye and watchfull insomuch that we had been unable to get a shot at them; when at rest they generally seelect the most elivated point in the neighbourhood, and as they are watchfull and extreemly quick of sight and their sense of smelling very accute it is almost impossible to approach them
