Emerald Cave of Black Canyon: The green water is clear because the Hoover Dam captures all the silt. The water's color is mesmerizingly gorgeous. This cave can only be reached by small watercraft (canoe, kayak). What a great adventure.
Black Canyon Overlook on an overcast day. The amazing volcanic rock possesses red, purle, black and brown colors. The lighting changes bring out various colors. The green Colorado River below is beautiful, just gorgeous.
March 2016: Nest and Tree Surrounded by Sand Dunes. The North Algodones Sand Dunes is a protected wilderness area with incredible sweeping sand dunes. A lonely tree stands lost in the middle of these imperial dunes. Amazingly, it contains a nest and shows signs of life in this dry place.
