The cave, which is known by the miners as the Aztec, is located 
about four miles south of the Graterville placers, in a limestone 
ridge. Quite recently a party of miners numbering eight or ten, 
including Mr. Coyne, explored seventeen rooms in all, the corridors 
and approaches to which extended for nearly a mile from the 
entrance. 
The cave has two entrances, which lead into an oval cavity, 
thence a corridor leads into a large room, and thence into a still 
larger. In from the latter are two smaller cavities, and these 
comprise the extent of former explorations. In them have been 
ound at various times in the past relics of Indian occupation, in- 
cluding arrows and skeletons, In one place several Indian skele- 
tons were found in a depression in the floor of the cave, evidently 
fashioned by human hands. This latter room is described as 
largest in the cave. From what was called “ Hale’s room a 
party followed a steeply inclined tunnel seventy-five or eighty 
feet long, which terminates in a large abyss sixty or seventy feet 
in diameter. After lowering one of the party down the perpen- 
dicular sides from the mouth of the tunnel as far as the remaining 
rope would permit—about seventy feet—and failing to find bottom, 
the explorers named it the “bottomless pit.”"—Zucson Citizen.
