This summit is right across from the Cement Plant off Hwy I-84 between Baker City, OR and Farewell Bend, OR. Looked like a nice option for a quick activation when traveling Hwy I-84. However, the obvious road to the top was chained with a sign stating permission required. No contact info, so must be locals wanting to keep people off the land. There is also a radio facility near the top, so the chain and sign keep people away from that area as well.
On Google Earth, there may be other less obvious "motocycle" trails to the top, but would have to be adventurous.
There should be cell coverage on top or near the highway. However at the chain, there was no cell coverage. APRS coverage in the area is good.
