May have hallucinated this, or seen ghosts, but in early July 2005 was detouring around Never Summer Wilderness in Colorado by going through Rocky Mtn Nat Park. Was headed south from the Bowen/Baker trailhead to the Bowen Gulch trail, to get to Bowen Lake, a popular camping spot. Although adjacent to mountains, this section of trail was quite steamy with a lot of leafy brush, and felt more like hiking in the southlands than in northern Colorado.
A young man in a blue civil war union uniform and cap, but with no insignia, passed me coming the other way (north), and responded a little gruffly to my greeting. Behind him was a young woman in a long dress, looking pregnant, with a large trunk strapped to her front. It was heavy and large enough that she had to lean way backward to walk. She must have been incredibly strong.
After they passed by, I did a kind of doubletake, but just kept on going. After the trail turned westward and went up Bowen Gulch, it was a relief to run into a couple who I camped near overnight. They had some nice dogs and offered me fresh trout cooked in one of those big frying pans. Felt back in reality.
There is a book entitled "Lost Nation," written by a college professor in Vermont that graphically describes how women were treated in the wilderness of northern New Hampshire in the days of the Indian Stream Republic. It felt like I'd walked back in time.
