Hiatus: Some Geological Truths May Never Be Known...

A hiatus in geology is a significant interval of time where there is no rock record in an area. The boundary between the two beds is called an unconformity. Here a granite deposited 1,100 million years ago is directly touching a 500 million sandstone.  This unconformity represents a 600 million year hiatus.

When People Ask...

When people ask "How can you get lost in a town of 30,000 people?," this is why.

"South. You keep using that word. I do not think it means what you think it means..."

Glaciers in Illinois and New York

If you live anywhere near the Great Lakes, then the evidence of glaciation can be seen all around you. You just need to know how to look!

Here a river has cut through a glacial feature known as a moraine. It's in a forest preserve in Palos Hills, IL, which is is just outside of Chicago. That's me. Picture by my friend Tom.

Cool Karsts

At first I was annoyed that we weren't going to the site we had planned and were instead going to a quarry almost an hour away. I wasn't annoyed once we got there.

Grown-up Moves

I should have been tipped off when every person I talked to said "You're moving? Wow. That sucks."

Some friends say that they'll go to hell and back for you. But how many friends are willing to go to Cleveland at 3 am for you?
