I did a snowline exploration on Saturday. Went up the Mason Lake to Mt. Defiance. The parking lot was full to my suprise. The steep part of the trail was clear of snow to the rockslide. At the slide I met a large party (Mountaineer') turning around because of the snow. The slide was entirely snow covered but easier to cross than when bare no real holes yet, do not know how long that will last. Devils club was not yet out on the other side slide but there were some blowdowns in the place where the trail used to be. Mason lake is still frozen with 6’ of snow around it, nice flat rock sticking out near the campsites. I saw footprints directly up ridge to summit of Mt. Defiance and met two guys who had kindly kicked steps on the near perfect snow. Fantastic view from Summit still looked like winter. Lakes Kullla Kulla, Rainbow, Blazer, and Pratt all appeared to be snow covered also.Ice axe was manditory as there is no good run out on descent.
