PCT south from Tamarack Trailhead to Wet Meadows

Message I rode my horse on the PCT south from Tamarack Trailhead to Wet Meadows yesterday. There are a number of trees across the trail and user created trails to get around them. I was specifically concerned about a tree which has fallen along the trail at a stream crossing. 38.61039, -119.88997 are the coordinates of the pin I dropped. My concern is the erosion happening when equestrians drop down a soft steep bank to cross the stream. It is also very unsafe for the horses and riders. We tried to find an alternate crossing point however there was nothing else available.
