Historic Columbia River Hwy 5th May 2022
The east and west tunnel diggers have shaken hands and given birth to the continuous length of the Mitchell Tunnel. What one instantly realizes is the light that comes in and creates the reminiscent older Mitchell Point tunnel. The curve of the ceilings and tunnels itself are taking shape before our eyes. Each adit is now showing its own personality with the Northerly view of the Columbia and Washington shore/mountain outlines.

The Mitchell Point is a patchwork of different lava flows and riverbeds over the past 15 million years since the Missoula Floods. The discontinuities of flows, variety of heat creating pyroclastic flows is ever present in our view.
