The Baker's water supply came from a hand dug well close to the cabin, likely located by dowsing, where a strong underground stream can still be found and where the well extended about 25 feet deep and often held water within 15 feet of the surface. The current pump is more modern, and each May a club of dowsers demonstrates and teaches the art of dowsing to 4th grade school children. Between the pump and the shed, grape vines on the arbor date to the 1800s and appear in the earliest cabin photos, while a lilac bush is a cutting from a plant brought from Calaise, Maine, in 1842 by Phillip Foster and his wife, who traveled by way of New York, around the Horn to Hawaii, then to Vancouver before planting their cuttings near Eagle Creek at what is now the Phillip Foster Farm Historical site. Horace, a skilled stone mason, owned and operated Baker's Quarry on this basalt mountain and chose this place for his Donation Land Claim because of the fine nearby basalt rock. Rock was taken from the base of the cliff rather than quarried from the cliff face, and stones were hand drilled and split with black powder or wedges. Large quantities of this stone went into the Tillamook Lighthouse, the Oregon City Locks, Pioneer Courthouse, and the Portland Hotel, with an example of the rough hewn stone placed near the cabin chimney where quarry marks remain visible. The stone was carried down the Clackamas River on barges to meet steamships in Oregon City, and the barges were later dragged and winched back upriver by men and teams of horses.
