Lost Viking Ship in California?

I wanted to know more about this story, as much as I can. I’m hoping I can catch someone who lives in this area of California, namely near the Anza-Borrego State Park. I’ve studied Vikings and this “supposed lost ship” story always intrigued me. I want to know if anyone else has heard more details.

The story goes like this (from a website):

“It was 1933, and Myrtle Botts was traveling with her husband, enjoying the famous annual wildflower bloom in what’s now Anza-Borrego State Park, in the Colorado Desert of inland southern California. They met an old prospector who swore he’d seen the remains of a Viking longship protruding from the side of an arroyo, well enough preserved that the distinctive round shields were still mounted along its sides. He wrote directions for Myrtle on how to find it. A paper, purporting to be those original directions, is preserved at the Julian Pioneer Museum in Julian, California.

Following the directions, Myrtle went and found the ship. She returned to fetch her husband along, but before they could get there, an earthquake brought down the wall of the arroyo, access was blocked, and the ship has not been seen since. Erosion in the arroyo has since washed away whatever the directions may once have led to.”

If anything, it’s just an interesting lost ship story, not necessarily from Vikings.
