This is one of the craziest geological formations I’ve ever seen.

My buddy Eric recently moved back to the area after living in Las Vegas for the past few years. I told him recently about my goal to climb one mountain a week in 2011, and said he wanted to join me for the next one.

I chose Step Mountain (6,117′ or 1864m) because I was struck by its incredible geology. It looks like someone stacked a bunch giant of railroad ties in a pile. Except that each railroad tie is a basalt column.

There’s a lot of rock in the Salt Lake City area: limestone, sandstone, quartzite, granite, cobblestone. Each type of rock is different to climb on. Granite is smooth with beautiful cracks. Limestone is sharp with lots of pockets and holes. Quartzite cracks are jagged. I was intrigued when I saw photos of Step Mountain because I didn’t even realize there was basalt nearby. As an avid climber, I was keen to check out the rock to see if it was climbable.
