Hospital growth forces big Boise sequoia move

An aerial view shows heavy machinery used by workers as they pruned the roots, built a burlap, plywood and steel-pipe structure to contain the rootball so they can move the roughly 100-foot sequoia tree in Boise, Idaho, Thursday, June 22, 2017. The sequoia tree sent more than a century ago by naturalist John Muir to Idaho and planted in a Boise medical doctor's yard has become an obstacle to progress. So the 98-foot (30-meter) sequoia planted in 1912 and that's in the way of a Boise hospital's expansion is being uprooted and moved about a block to city property this weekend.
