This coming weekend, 18 and 19 July, 2009, will feature the annual "Bannack Days" festival at Bannack State Park, Montana. Bannack lies in the southwest corner of Montana, just over a pass from the Big Hole, in the heart of Lewis and Clark country, and some 30 miles from Dillon, the "capital" of Southwest Montana located along I-15 south of Butte.
Bannack Days includes sourdough pancakes at the Hotel Meade, quite a number of authentic 19th century crafts, black powder rifle exhibitions, gold panning, re-enactment of the Sheriff Henry Plummer vs The Vigilantes showdown, live music, and other period (and modern) foods, all in the setting of possibly the best-preserved ghost town in the West. Bannack also served, briefly, as the first Territorial capital of what was then Montana Territory, in 1861-1862.
I've been to Bannack 4 times over the last 31 years, with the first having been during a geology school field camp in July 1978. On the third visit I stumbled upon Bannack Days, and on the 4th, I planned my trip to include it. It's entirely possible to see quite a lot of Bannack Days and visit Lemhi Pass, where Lewis and Clark first crossed the Continental Divide, all in the same day.
It's the real thing, in the real "Marlboro Country". If you're anywhere in the vicinity, I recommend checking it out!
