5497 is a 4-point summit in the Malheur National Forest, about 23 road miles northeast of Prairie City, OR. It is about a 1 mile road walk/bushwhack (each way) to the summit through open terrain and forest. The area is closed to motor vehicles but has good remnant roads for walking. The summit is semi-open, no views and plenty of trees for antennas. Don't expect 2m contacts here and AT&T data service was non-functional, so I relied upon RBN for spotting. I didn't think to check APRS.
Drive to and park at (44.65281, -118.53027) and proceed east towards the summit. You can cut up early and work across to the ridge (as I did) or proceed on the road a bit and then cut more directly to the ridge. Not much difference really. I recorded my track (up and down together) so you can see some example routes.
