When you live in the mountains, you learn to dress in layers. Before there were any moisture wicking fabrics or "exercise wear" outfits, we at the Yosemite Institute wore 3 layers to stay warm. A patch for our Environmental Education Organization of a lone Jeffrey Pine atop Glacier Point was sewn onto the cotton shirts, the blue wool Woolrich overshirt, and the heavy grey LLBean Flannel jacket that were standard issue each year I taught there.
We supplied our own pants, footwear, and hats. I wore a red wool beret in the winter and a scarfs tied like a pirate in the summer. I wore hiking boots that were never quite water proof enough, called Muir Trails, that I loved. Later, in my 3rd or 4th year teaching in Yosemite, I took to wearing knee high rain boots for much of the winter time- drier feet with less arch support.
For rain gear we were on our own. There were instructors who invested in polypropylene outer wear. Me, I found a "Kool's Menthol" green rain poncho in the lost and found and would throw that over me when the precipitation wasn't snow. I usually wore jeans or shorts in the warmer months, and a pair of wool pants when it was cold. We taught at altitudes ranging from 4,000-6,000 feet, so we were on cross country skis a great deal in the winter.
Describing my outfit for my years teaching at the Yosemite Institute brings me great memories. When I finally left, I had several stacks of untouched "warm when wet" grey jackets, as I only used my original during the five years I taught there. It served me well.
