Granville Stuart met Henry Plummer and Charles Reeves at what he called Beaver Dam Hill, but on present day maps is known as Beaver Tail Hill. From a diary entry by Granville's younger brother James, we learn that Granville left Gold Creek on September 10, 1862 for Hell Gate, which was a day's journey away. Beaver Tail Hill is half way between Gold Creekand Hell Gate, which means he met Plummer that same day.

Plummer and Reeves went back down to Hell Gate with Granville Stuart, and they all returned to Gold Creek on September 18. 1862.

You may view the actual DIARY ENTRIES from 1862. These diary entries are from pages 222-223 of The Montana Frontier 1852-1864, by Granville Stuart. The entries marked J.S. are from Granville's brother James. The two brothers were prospecting and running a store and blacksmith shop at Gold Creek on the Clark's of Deer Lodge and Missoula, Montana.
