This past Wednesday, Grand Canyon National Park's Interpretive Rangers lowered the flag in honor of one of their own. A ranger who lived and worked at Grand Canyon National Park for the past 20 years, and became a favorite of visitors from far and wide. Ron Brown.

After forty-eight jobs in five states, Ron Brown found his calling as an interpretive park ranger. He passed peacefully in his sleep at his home in Grand Canyon Village.

Ranger Ron's popularity among Grand Canyon visitors was undeniable. One of the programs he was best known for was his portrayal of the tall-tale spinning "Captain" John Hance.

The deep canyons of the west enchant us today as much as they did those who dared to explore them for the first time. They're all unique in their own ways, as nature seems to brag about the incredible might of its gem-cutting rivers. But one Colorado canyon, in particular, is like none of the rest. It exposes you to some of the steepest cliffs, oldest rock, and craggiest spires in North America. Over two million years, a river has sculpted this vertical wilderness of rock, water, and sky that, in parts, only receive 33 minutes of sunlight a day due to its steep, narrow split — giving it an ominous name, The Black Canyon.
