We were on snow from the parking lot at Rattlesnake Ledges. The trail was packed down snow the whole way, with a few icy patches around the (upper) parking lot and on the trail. Our hardy party used microspikes right from the cars. There was only one other party at the ledges while we were there.
Open views from first Rattlesnake Ledge allowed observation of an impounded glacial lake bottom at the head of the Middle Fork Snoqualmie River, the continental glacier lateral moraine (Grouse Ridge) and impounded lake bottom at the head of the South Fork Snoqualmie River and the lake bottom, lateral moraine and Boxley Blowout scar of the Cedar River valley. There was a glimpse of an elk near the parking lot.
