It rained for two days, and the water at the end of the lake at Tasman Glacier Lake was milky white, the color of the surrounding rock, gravel and mud water into the lake. When I walked to the middle part of the lake, there were still some lake ice that had not been melted, or crystal clear, and there were cold water fish activities in the lake. Although there is no sun, the lake is still blue. Take a look at taking pictures, the Tasman Glacier Lake itinerary is enough for1-2 hours, plus the Hook Valley Glacier Lake 3-4 hours. If you don't watch the stars at the Hook Valley Observatory, friends with tight schedules can not live in the valley.
