Growing up in Skagit and Whatcom counties and knowing Dallas back in the day, this is probably the most interesting piece of PNW climbing literature in my collection. Published in 1971 and sold as a 67 page pocket guide for $2.50.
Mine are probably a bit more recent and some of these are not really PNW, but some of my favorites in the greater region… or by people from it… that are not standard fare I think? or at least getting rarer and out of print.
