Sunday during our trip to Crater Lake, we stopped at a visitor information site. I liked the architecture there; it was designed to handle the ten months of snow which lingers at the high elevation of the lake.
Of course, I had to take a close-up of one of the signs because I really liked the typeface. The serifs make the signs easier to read, and the drop-down stems on the R's, the M's and the N's make this type face feel like a more laid-back copperplate.
Curious, I visited the National Park Service's typeface page: http://www.nps.gov/hfc/services/identity/typefaces.cfm, but neither typeface listed there is what this sign is using. It's not a part of their signage page, either.
Looks like a mystery to solve!
