Branstree is a Lake District fell of 711.5 m in Westmorland and Furness. Its key col leads to High Street, not to its nearest higher summit, Harter Fell (Mardale).
Its drop of 137 m makes it a Hewitt but is short of the 150 m a Marilyn needs. The highest point is recorded as ground 80m nw of end of wall, not a cairn.
