"Sure he (Astaire) was great, but don't forget Ginger Rogers did everything he did backwards...and in high heels!" -- Bob Thaves
For the women who visited Yosemite in the mid-to-late 1800s, the trip was no walk in the park. Before there were roads into Yosemite, there were steep, windy trails and women had to traverse them on horseback, same as men. But unlike the men, women weren't wearing the pants. No, they were dressed virtually the same as they would have been in the city -- chemisettes, corsets, blouses and jackets on top, with long, heavy skirts and multiple crinolines on the bottom. Completing the look was a bonnet -- offering protection from the sun and dust, but often heavy and cumbersome too.
Add to that the need to ride sidesaddle to accommodate both manners and dress and it's a wonder any women chose to come to Yosemite at all. But they did, bringing with them their good manners and good breeding because, even as early as the late 1860s, Yosemite was not the Wild West (unlike the Gold Rush towns that surrounded it), but a tourist destination.
