"Timber line" by Alida Malkus is a novel written in the early 20th century. Set high in the Rockies, it follows Dawn O’Neill, a forest ranger’s daughter, as she defends meadows, wildlife, and water sources against trappers, overgrazing stockmen, and political schemers. Threaded through the conservation battles is a quest for the legendary Silverstake Pine, a boundary blaze tied to Pueblo rights and a rumored silver vein, and a budding alliance with an irrigation engineer who shares her reverence for water. The opening of the story paints a vivid mountain world: a lobo escapes a trap at the cost of a paw; Dawn discovers and springs other traps, then returns to the cabin where she and her father debate predator control, overstocked ranges, and the disputed reservation boundary marked by the lost “Silverstake” pine. We meet Hinray Dorsay and hear of trespassing goats and careless grazing that scar the meadows. Dawn drives a large herd of goats back into their pasture, locks the gate, and escapes two angry herders by swimming her pony across a cold mountain lake, where she encounters irrigation engineer Garen Shepherd; they quickly bond as she shows him a hidden waterfall and a subterranean stream, and points out the distant giant pine she suspects is the old witness tree. A struggling rancher named James seeks fair range help, which Dawn offers, while a wealthy banker, Perry, and a smooth lobbyist, Gershwin, arrive intent on “opening” the reservation and expanding range. Guiding them, Dawn explains the science of deferred grazing and watershed protection; they witness a government hunt that flushes a lion and the fabled lobo through the trees. The section closes with Gershwin probing for rumors of silver as the political and environmental stakes sharpen. (This is an automatically generated summary.)
