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 around the summit is closed to motor vehicles but has good remaining 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. The mainline gravel roads in this area are excellent. 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. It is available in SOTA Maps and SOTL.as
NOTE: If you are using Gaia's base map and it looks like there is a road from the east/southeast towards the summit, there isn't. Use the Forest Service map of the area and approach from the west.
