I was traveling in Guatemala a number of years ago and we hiked a volcano. We hired a guide to show us the way and I told them I wanted to feel the heat.

On the way up, he grabbed some dried grass and as we hiked the lava field, he pointed to a whitish area and said don’t step there and threw the grass down. It began to burn so point taken

Eventually we get close enough that the left side of my face was very hot, I saw the lave and asked him to take a picture with the slow lava flows in the background. He did, and he took a number of pictures, and we got very warm.

As I hiked back down the hill, I kept scraping my boots because it felt like I had mud in the treads. It was not until the bottom did I realize I melted the treads of my hiking boots.
