I have hunted the WPT land for probably the last 10 years. My son and I spent a couple days in various parts this last year and hiked a lot of miles.
As for Turkey I have only ever seen 1 hen with a lone baby while on WPT land and a few tracks in the snow otherwise all the turkey I have seen has been on posted "no trespassing no hunting" private land and I see lots every time I'm up Cedar Valley Rd. As for maps of WPT land good luck finding anything from their website. I have only found maps through internet searches and using the interactive parcel mapping on the Klickitat county website.

It's public record but will refrain from posting his name. I was really hoping it would stay open. I know an alternate way to access the remaining WPT land to the North along the Reservation boundary but will likely need a truck to drive in and I don't have one. My son and I were talking about doing a couple day pack trip into that area this next season.
I know WPT was logging West of Cedar Valley Rd. and South of Lower Rd. last year during the late archery season. I drove by the crew stacking logs and there was an area closed sign at the gate on Lower Rd.
It wasn't un common to see 15+ deer a day on the WPT land but now I'm lucky to see couple. The population has plummeted that's why Grayback has went 3-pt min. for archery this year.
I do hope some of the timber land does remain open and accessible from a gate.
