Memorandum: 188? Walla Walla, December 9, 1887.-Several years ago a loud explosion somewhere in the Salmon River Mountains shook the whole country there, and reports of a volcano breaking out and lava flowing over the mountain trails astonished the country. The San Francisco Chronicle and Portland Oregonian sent reporters there, but neither could find any trace of a volcano, though whole forests were ablaze. Joseph Baker, of Mount Idaho, an old miner, reports to the Walla Walla Statesman to-day that he has discovered the scene of the explosion, near some new diggings. The country for half a mile around is full of fissures newly cracked, but there are many others cov- ered with moss, denoting previous explosions.-San Francisco Chronicle, December 10,1887. The place is only twenty miles from Mount Idaho.-Walla Walla Statesman, December 9, 1887. [This record should have been under Idaho. See August 8, 1881 in Idaho list.]
