Just made it back in from spending the day on the Su and Yentna Rivers. Trail from the Deshka Landing to the Kahiltnta River was in decent shape. Non of it appears to have been groomed with a groomer. Slight amount of overflow in the swamps and on Kroto Slough. GCI route was pretty much the one everyone is using. The bottom end of Kroto was getting worse for overflow, later in the day, on the way back out. The main trail was good going, but if you got off of it, you immediately went into 2-3 feet of powder. Very loose snow trail conditions. Several open leads on the Su, so I stayed on the main trail. I did not think it was ready yet, to go bombing off with all the new snow hiding the thin spots. All in all, it is good.
