That looks a lot like a place here in the Columbia River Gorge, Mount Defiance. When I was young, my dad had a two way radio transmitter up there for the loggers as part of his communication business. In the summer we used to 4-wheel to the top to the lookout tower where the transmitter and tower we built was. You can’t drive up there any longer, they put a gate up but you can get within a couple miles and then hike the rest of the way. In winter we took snowmobiles up with a trailer to bring propane up for the solar generator but it was super hard, the snow would get 15 feet deep so he bought a snowcat like they use at the ski resorts. One year we were going across a side slope and tossed a track and had to hike a few miles back to the truck, following the snowcat tracks but still sinking up to our waists. Things like this are why I don’t 4-wheel in the snow anymore. Got stuck in places that almost killed me too many times. If you go, be careful and pay attention to the forecast. I see here this weekend the Cascades are expecting 2-3 feet of snow and winds 40-50 mph. It’s the kind of weather that catches adventurers by surprise and they get in but can’t get back out.
