This Summer Rocks! Glacial Erratic

Welcome the first installment of This Summer Rocks! The first of 7 geology and gem inspired adventures. For this adventure we didn’t have to travel far. In a way, you could say this rock came to us. Learn about it in our travel journal…

We traveled to Hokum Rock which is 6 miles away from our house by car. It was hot so we stopped off at the ice skating rink to cool off on the way and crashed a birthday party.

Just kidding, we were invited.

It was not hard to find Hokum Rock since it is on Hokum Rock Road. Plus it was big and definitely looked out of place.

Hokum Rock is a Glacial Erratic which means it was brought here on a big piece of ice. This rock which is a type of igneous rock called diorite came all the way from New Hampshire more than 50,000 years ago and the rock itself is about 300 million years old! We walked around it. It had moss, lichen, and ferns growing on it. It also looked like a puzzle half put together with some sections of rock fitting together nicely and other broken away. Some of the breaks made cave like spaces and some made nice climbing steps.

We climbed to the top and looked down and around. Then we climbed back down which was actually a little trickier than climbing up.

It won’t budge!

Depending on where and how Glacial Erratics are placed they can look like they are balancing.

erosion

Because of erosion some have smooth tunnels and some have particularly beautiful or interesting shapes that can sometimes look like people or other things.

Nature inspires many artists. Isamu Noguchi is one artist inspired by natural rock formations.

Hokum Rock was a fun adventure even though we made Mom nervous while exploring the top. It was very hot so we didn’t stay long. We left in search of water but we would like to return and are pretty sure it will still be there when we get back!

  1. Great first story! Nico LOVES rocks, can you believe we moved a small box of them across the country with us in the van? Oh yes, with us, because in case the movers would lose them, lol.
    We have special rock formations about 1h30 by car from us, they are called the Hoodoos, they are pretty funky. We hope to take Nico there this summer :)

    • Neat, I’ll have to check it out online and yes I can totally understand why Nico would want to keep his collection safe during the move :-)
