There was a time our 5th graders attended the Sierra Outdoor School (SOS) near Sonora for outdoor education. Before they arrived to do the Duffle Shuffle at their new digs, they headed over to Murphys to do some spelunking at Mercer Caverns, so I thought I wouldn’t mind heading 16 stories underground.

This cavern system is not for the faint of heart, the exceedingly tall, or the claustrophobic.

It was “discovered” by its namesake Walter Mercer. Why the quotes? Well native Californians knew of the cavern’s existence at least 1,500 years ago and native remains were found in the caverns.

But on September 1, 1885, Mercer chanced upon the caverns in a search for water. He failed as a gold miner but struck pay dirt with this discovery. Here he was mining the tourists and thrill seekers.

Our guided tour lasted about 45 minutes and luckily I only hit my head once (near the exit).

It was also near the exit that Mercer took a big fall when his rope failed and he fell 30 feet. The fall killed him, it just took twelve years to do so. The fall caused injury to his neck and back and this later led to tuberculosis of the spine. He finally died from his fall on November 1, 1900. Mercer was 46 years old.

While I could not bring my sketchbook into the caverns, I was able to sketch the shack near the entrance. And there was a seated shelter to protect my sketch from the drizzle. This provided the anchor of the sketch.
