I’ve been in some that were no big deal at all. More work than the same mileage without blow down, but I still did 23 miles that day. I’ve also seen some that I didn’t even want to try.
Your screenshot doesn’t look too bad. Sometimes satellite photos tell the story, and sometimes they don’t, at least to me. A radiologist might read a satellite photo a lot better than I do.
The one that I traveled really well in was pretty thick and looked bad, so it kept other hunters out, but it really wasn’t bad. Most of the logs were 18-24” off the ground with all the limbs burned off, and they were 10-16” in diameter, so you could step over or onto them without climbing, and when they paralleled your path, you could walk the length of the log easily, and often step directly onto the next log. I’ve seen others where the trunks were smaller diameter than I would want to walk along, and I’ve seen them with limbs mostly intact, so they would be an absolute disaster to try to go through. They’re all different.
The pic below was truly easy travel. Had limbs been intact, it would have been impossible.
