Hike about 5.5-6 miles. Steep at the start then slow descent the rest of the loop. Maybe a quarter to half mile total of icy trail - very slippery, each of us fell at least once. The end of the loop on High Drive and portion right near it may be actually closed still due to the old flood damage from last season, but people were hiking on it anyway. (Total hike distance for season about 32 miles.)
This was a bit puzzling as to cause - is there a pipe under there that burst?
