The Natural Bridge
Rogue River Gorge National Forest, Oregon
Pictures taken July 15, 2008
It began as a...
River of Fire. When basaltic lava flowed from the fissures in the earth's surface and travel long distance through lava tubes.
Lava tubes develop when the upper surface of the basalt flow rapidly cools, causing the outer edges to splidify, while the hot inner lava continues to flow underneath. As the molten lava drains out, it leaves behind a long hollow tube.
Eventually, the river of fire was replaced by a...
River of Water.
The Rogue River entered a section of a lava tube, becoming a "hidden river" which flows below ground for 200 feet. In doing so it created a natural bridge that connects the bank of river.
Indians and early settlers used this natural bridge to cross the Rogue River.

It's close to lunch time.
We will be back here later this week.
