On a recent camping trip to Riffe Lake, I activated this summit after activating Burley Mountain (W7W/PL-039). See my other trip report for directions to get there.
The route we took after Burley was to continue on NF-77 from the junction with NF-7605 and follow it until the junction with NF-202 at (46.344296, -121.927806) There is a spur at this junction (NF-7700201 that heads north a short 1/4 mile to the summit.
The activation zone is a small clearing surrounded by trees with no view.
I had no trouble raising my EFHW and making a good quantity of contacts on 20m/40m, along with a few S2S on those bands and 2m.
NOTE: If you are coming from NF-25 and starting with French Butte, then turn onto NF-28 and follow that up until it reaches the previously mentioned junction of NF-77 and NF-202. However, NF-28 is very dusty (read, it's probably a mud pit in rainy weather) and there are lots of ruts and rocks so it might be better to start from Burley and then retrace your path if driving a passenger car.
