Centuries old yellow pines trees, infected with bark beetles, would otherwise have been taken for their lumber -- but the owners of Lost Trail Hot Springs had another vision in mind.  Chainsaw Sculptress Lisa Foster was hired to carve likenesses of Sacajawea, the teen-age Shoshone guide who lead Captain Lewis and Clark on their journey west.  Lewis & Clark, Chief Joseph and Jeremiah Johnson have been commemorated by Foster who has carved their statues from the 14-foot to 22 foot high yellow pines stumps prepared by a sawyer.
