With UN 13,075 and Treasure Mountain.
Up from ex-Lake Emma (thank for your account of that extraordinary chapter in mining history, Liba)
Did a loop over Hanson, Bonita & UN 13,075 while on a winter trip to Silverton for my birthday.
Nice hike from drained Lake Emma site, went up Hanson and then over to UN 13705.
Climbed as part of a long loop tour of California and Placer gulches. Started up Treasure, traversed over PT 13075 and Hanson to Hurricane then dropped to California Pass before heading over Tuttle and Houghton and back to the car.
