Almost night over Holy Monastery of Roussanou at Meteora, Greece. Sitting on the edge of another cliff like this and with a flashlight on my forehead ,(as it was almost pitch black night), i waited patiently ,with a friend, for a car to pass by, ..with no much luck. Thankfully 2 motorcyclists rolling slowly downward, while talking to each other, gave me this 60sec long exposure with enough light to light the rock ;)
Jacob's Well in Wimberley, Texas. It's a significant karstic spring, the largest perennial spring in the Texas Hill Country. It flows from the most extensive underwater cave in Texas. 4m diameter mouth cave, descends vertically for about 10m, continuing from there at an angle as a series of chambers separated by narrow, often deeply silted and unstable necks, ultimately reaching a depth of at least 40m.
