Fantastic moderate two pitch ice flows. If these flows were anywhere else, they would be the 4 star classics of the area; they just get mentioned less because of the insane climbs to the left. The Tablets are generally split into three sub-areas: Tablets-right; -center; and -left. The difficulty increases from right to left. In general the right flow is WI3, the center flow is WI3+, and the left flow is WI3-4 depending on how things form (usually there is a pillar on the left side that checks in around WI4).
Use care on the top out because there is often rotten ice or thin ice covering loose ground (i.e. easy, but with limited protection).
The Tablets are on the far right end of the obvious flows at Willoughby. You can easily see the three Tablets in Kris Gorny's overview picture of Lake Willoughby. The three flows are to the right of Crazy Diamond in Kris' photo. Note that the Left and Center Tablets are more or less the same flow but are separated by a set of trees that extends about 1/3 of the way down from the top of the cliff.
