UPDATE July 2021 - There is now a no trespassing sign on the yellow gate.
The blue gate barring the logging road now bears a Weyerhaeuser No Trespassing Sign, and a second sign explains how to purchase a non-motorized recreational day-use permit from Weyerhaeuser. Go to https://www.wyrecreationnw.com/HomePage.aspx for details.
The good news is, there are no signs at all on the nearby yellow gate controlling access to a separate gravel road leading to some commercial communications sites. These sites are not at the true summit, but are within the SOTA summit activation zone. There is no view, but numerous deciduous antenna supports surround a couple of flat clearings. I experienced no HF interference from the communications facilities; however, my attempts to post SMS alerts failed in spite of "full bars". Overwhelmed by strong UHF or microwave signals?
