My family settled in Grover, WY in the early 1880's. There are tons of stories passed down about Butch Cassidy and some of his "Wild Bunch" members being here in the area for long periods of time.
I'll try to tell you what I know in the shortest version as possible. My family's first accounts of Outlaws that rode with Butch Cassidy was in 1887. Tom McCarty and another person (name not known) came into Star Valley and started to build a cabin in the Auburn Area. The way I understand it at this time no one was aware Tom was a outlaw. Tom returned back to the area and finished this cabin with Matt Warner in 1888. It sounds like McCarty and Warner spent most of the 1888 summer in the area. Or they could have just been back and fourth from place to place. They left the Star Valley area in the fall of 1888, They didn't come back to the valley again until mid summer of 1889. (This places Tom McCarty and Matt Warner in Auburn, WY right after they robbed the Telluride, CO bank in June of 1889 with Butch Cassidy. However Cassidy didn't come to the area with them at this time. Cassidy was said to be in the Lander area after the Telluride Robbery. Tom McCarty and Matt Warner stayed at the Auburn Cabin throughout the winter of 1889. They where well known and liked in the area. I'm not sure if anyone even knew they where outlaws at this time. The winter of 1889 was extreme and rough. So much snow that goods couldn't get over the surrounding mountain passes into Star Valley. Tom or Matt (not sure which one?) held a local store owner at gun point to get the owner to loan goods to people of the area until spring. In a way they kind of became local heroes for this action. Tom ended up Marrying Sara Lemmberg. The Lemmberg's where the first family to settle Auburn. Sometime after Matt married Sara's sister Rose Lemmberg. Cassidy showed up in the area for a very short period of time in the summer of 1890. The three gang members where in and out of the area the whole summer. The next big thing wouldn't happen till 1891 when Cassidy came into the area with Al Hanier. I guess at this time Matt and Tom where not in the area. Cassidy and Hainer where arrested in Auburn WY for horse theft in 1892. In 1896 Butch Cassidy would be in and out of the area with outlaws Elzy Lay and Bub Meeks. Around this time Matt Warner ended up in Jail. Rather then bust him out the gang made a plan to rob a bank in the area to get money for a lawyer. On August 11 1896 Cassidy, Lay, and Meeks went to a few different ranchers in the Star Valley area and bought horses. It was later realized they staked these horses in the Crow Creek area between Montpiler, ID and Afton, WY. To switch with their wore out horses after the robbery. on August 13 1896 the three robbed the bank in Montpiler Idaho and made for Star Valley, but they quickly ended up leaving and going toward Lander. This is last info I have of Butch Cassidy, or anyone who rode with him in this area. Not sure of some of the exact dates, it's info I jotted down over the years when my great grandpa would tell these stories, and they got passed down over the years. At one point in time the guys plastered one dollar bills on the walls inside of Matt's cabin. Not sure when exactly they did that, but I would guess it was right after the Telluride Robbery. I think Butch Cassidy and a lot of people that rode with him spent some time here in this area. However there are no stories or info of the Sundance Kid ever being in the area. Even though it's not as focused on in the history books I think this was just as big of a hideout for them as the famous hole in the wall. Probably a great winter hideout since the valley would be snowed in during the winters. This area is around 60 miles south of Jackson Hole, and Jackson was starting to boom in the late 1800's so I wouldn't doubt Butch Cassidy made it to Jackson at least once if not more. I just remembered Cassidy was supposed to meet with some lawmen in Jackson Hole sometime in the middle of all his robberies. They where trying to make a deal with him, but The lawmen didn't show up at the meeting location due to a major snow storm and Cassidy figured he was being set up, and took off. So according to this story he was at least in Jackson once. Hope this helps you Tiredman.
