I'll ramble on for a bit about my experiences with my choice of clothing for that day, and about the weather, and maybe some other things. The weather forecasts said there would be a pretty good chance of rain all day, with a slight chance of a thunderstorm - But Katahdin sort of has it's own little weather system going on over it, so who really knows.
My clothing and gear for the day was a linen undershirt and braes; the cut-off particolored hosen shown elsewhere on this site, pointed up to a light wool pourpoint; tall and thick woolen knitted stockings, held up around the knees by silk garters; my gray Rock/skirted doublet; and on my head, my wide-brimmed red hat over a wool coif... pretty much my standard outdoors-in-the-woods-wear for that summer. I also had a nice ebonized walking stick that I made the day before, which turned out to be a perfect length for wedging under my arm to lean on like a crutch and really helped in clambering up some parts of the trail. I'd seen many period (from several different centuries I believe) images of pilgrims carrying stuff slung over a staff on their shoulder, almost in stereotypical-hobo-fashion, so I tried that for a bit with my otter skin bag, and it worked very well for the flat areas of the trail at the top and bottom of the mountain - but for many parts of the trail I was actually using the stick for walking, for a little assistance with climbing, or just tossing it up over the rocks I had to climb up on the trail (or down over the rocks on the way down... my nice ebonized piece of driftwood walking stick carried many scars home with it at the end of the day).
At the time I think it seemed like a hellish hike for all of us, no matter what we were wearing because all of us accept for Aaron were rather out of shape from not doing much other than sitting behind desks for a few years. I remember thinking at the time that now that I've done this I don't ever need to do it again... but I often get a similar feeling while sea kayaking - "oh crap! I could die right now!"... but I'm still here and as always, that feeling is soon forgotten and I want to go out again to do something similar; and following in that pattern, I'd like to climb parts of this mountain again sometime and take along some of my recreations of 16th century climbing gear as well.
I think all of these photos, except for the ones with him in them, were taken by Aaron.
