[leadin]You may have seen our post on nocturnal ice climbers and glowing waterfalls earlier this year. Part of that same crew, including photographer Matt Holland, were at it again.[/leadin]
This time the medium was rock, and the area was the Horseshoe Canyon Ranch in Arkansas. Holland coaxed his climber friends to wear glowsticks and lighted necklaces and climb vertical rock at night. His Canon 7D camera soaked in long exposures (three to five minutes) to capture the trippy scene.
