Bonanza King Mine and Providence ghost town,
Providence Mountains, San Bernardino co., CA.
We both woke up at sunrise this warm
morning. While I was my hiking gear ready,
Bruce found a grey Speckled Rattlesnake
asleep under a limestone boulder. We both
Got our cameras and took some photos of it.
Then we hiked up the main, north fork
of the narrow, steep sided grey limestone
canyon above the mine. The canyon bottom
was very brushy with dense Desert Almond
bushes and large catclaw acacias that had
not leafed out yet. Above the rocky wash
bottom, there were grasses and Agaves on the
steep canyon sides.
We put in five pitfall traps at the
intersection of the large south fork with the
main fork of the canyon. This was at the lower
limit of P?on Pines in the canyon. Our traps were
plastic five gallon buckets sunk into the ground
so that their mouths were flush with the ground.
We covered them with dead, fallen shrub branches
and rocks, leaving enough space for small animals
to crawl through. Digging the holes was very
hard work; we moved more rocks than sediment
and soil.
