Mountains tangram puzzle

A mountain range with three peaks side by side, all rising from one flat base. It is rated medium because the peaks say where triangles might go, but the range is one low solid mass under them. Well over half of the pieces' edges are hidden, which leaves it just short of hard.

Drag the seven tangram pieces onto the shadow until the mountains is filled. Every shape here uses all seven, with no overlaps and nothing hanging over the edge. The pieces have exactly the silhouette's area, so covering the shadow is the whole win condition.
