I never imagined a simple walk through the Sonoran Desert would shatter my whole understanding of life and death.

But that’s exactly what happened on a Tuesday morning in late October.

I’m Jack Thompson, a retired geology teacher from Tucson. Hiking is my therapy. The dry air, the vast silence—it clears my mind.

That day, I’d gone off the marked trails near an old dry wash, hoping to photograph some rare cactus blooms.

The sun was already scorching, and the ground crunched under my boots, a mix of gravel and baked earth.

Then my right foot landed on something that didn’t give way like sand. It was hard, oddly shaped.
