Salt Creek pupfish, an endangered species in Death Valley National Park, Spring 2012




During the spring, the endangered Salt Creek pupfish males set up territories in Salt Creek as if flows from a spring south to the below sea level section of Death Valley National Park. The pupfish are considered the remnants of fish that once inhabited Lake Manly which filled what is now Death Valley during the last ice age. As the water level receded as the ice age ended, the water became saltier and now only a few springs persist and provide the only habitat for this species. Besides the saltiness, this creek experiences flash floods, nearly drying out, and temperatures from near freezing to over 40°C. (104°F.)

This image was taken by hiking along the boardwalk of the Salt Creek Interpretive Trail, a short turnoff from Highway 190, between Stovepipe Wells and Furnace Creek, the two main developed areas within Death Valley. Rick got down on his belly and waited for a male to swim near the shore to get this shot. You can tell it's a male because of how colorful the front is and by the bluish dorsal fin. Females are better camoflouged and blend in with the grainy creek bottom.

Bull elk in velvet along the trail in the Sinkyone Wilderness State Park, California. 2014-08-08



We encountered this bull elk along the trail in the Sinkyone Wilderness State Park, California, while heading back to the trailhead during a backpacking trip. In early August, the elk's antlers would still be growing with the furry-skinned velvet covering them as they're growing. Later, when the antlers are finished growing, the velvet will die and slough off. Sometimes, the elk will get an itchy feeling from the whithering velvet and feel the need to rub the antlers against a tree or shrub to get the velvet to come off faster.

This particular elk didn't seem to have any problem with our presence and was actually lying down when we first came across him. Another bull elk headed downslope off the trail at a leisurely pace and got his antlers caught in grape vines.
