On June 23, RichmondOutside, Terrain360.com and the James River Association set off on a journey to map the entire James River — all 343 miles from mountains to sea. There were a lot of partners involved with the effort, but we couldn’t have done it without the financial and logistical support of the JRA.

On Wednesday (Sept. 17), as part of the JRA’s participation in The Amazing Raise, the group will host a party at the The Camel from 5-7 p.m., where we’ll show off the product of our labor this summer: An interactive, 360-degree, surface-level tour of the entire James River. This is a first-of-its-kind map of any river in the world. The full tour isn’t online yet, though it soon will be at Terrain360.com, RichmondOutside.com and EnvisiontheJames.org.

The public is invited Wednesday to see our presentation on the trip, and, if you’re feeling so inclined, give some money to the JRA as part of The Amazing Raise. In addition, local filmmaker Hunter Davis will be showing some of his James River-related short films. Entry is fee, but if you stay for the bands following us — The Silks, Mossetrap and Dr. Con — you’ll have to pay $5.
