Anyone who has spent some time soaking up at Scenic will probably have noticed the appreciable amount of tiny rock-like granules discharged at the end of the feed tube into the hotter pool (the one fed by the Lobster Pot feeds), while the feeds from Bear Den hardly deposit much more than a small amount of silt to the bottom of the pool. The Lobster Pot sources are travelling shallowly within decomposed granite and picking up some of those granite grains (the precursors to sand by the time these waters make it to the lowlands) before emerging to the surface.
Hopefully, in early-season melts like this, we would expect that winter is not quite over with yet and a cold snap of sufficient duration would re-freeze that shallowly traveling melt and lock it up . . . allowing Lobster Pot to resume it's normal temperatures. Colder weather is expected later this week . . . hopefully enough to abate this temporary dip in the temperatures of the hotter feed.
