JPL 1

The claim includes a large stretch of the river and there are multiple access points from the highway. Additionally if you wanted to access the other side of the claim there is a road shown on google maps that runs to it, though I can't speak for the condition of that road.

From the highway there is a loose dirt road that runs to the front of the claim, and then you can also access the tail end directly via the highway.

Traveling north or south along the I five You Take Highway 96 exit it’s right there by a big rest stop it crosses over the Klamath River and as you head west on Highway 96 enjoy the long winding curvy scenic road to the claim easy access off the highway large pull out you can use for a camper to camp and as well off to the right from the pull out is a small trail to a large gravel bar otherwise most of the claim is along the edge of the river where there’s good gravel boulders to dig through and some bedrock just west of the culvert .
