Sendimentary Rock Layering Exposed...

 

 I was returning from a job site last week in Western NH and my route took me through 

Milford on my way to Nashua to another site.  Route 101 bypasses the downtown area

and you re-merge onto 101A. Here is where these shots were taken from street view.

They carved the exit ramp through a huge rock outcropping and the layering is nice exposed.

 

When I went through there it was sunny in the afternoon and the lighting really showed the 

varying layers in all their glory.

 

Here is the street view link for those that want to search <<<

  1. You will need to zoom in & find your route, but Roadside Geology is a great way to learn. Some state police don't care about science so becareful where you stop. https://www.des.nh.gov/sites/g/files/ehbemt341/files/documents/geo-055-062500-smap-milford.pdf

  3. Similar gorgeous layered rock formations on the road (Rt 9W) from West Point (actually Camp Buckner) to Stewart AFB - Storm King Highway - a gorgeous daily trip one summer from the Stewart BOQ to teach at "Beast Barracks". The Cadets were LOCKED IN versus the snowflakes of todays schools.... it was a joy and an honor. Now when I see what is going on at AFA I thank God that I had what I had.

  4. Looks like gneiss which is metamorphic. And NH is the granite state for good reason. Igneous rock.

    Cool pics and doubly cool for being interested enough to post.

  5. You see that down in the south, that type of strata, limestone being laid down for millions of years.

  8. beautiful pictures. amazing to think how the layers were formed and then thrust to the surface

  9. each of those layers represents the time for sediments to accumulate between ice ages. about 25,000 years between them, so many, many layers there that you can see. gives you just a hint of how much of our civilization would still be around afterwards. nothing. and take a wild assed guess how long it's been since the last one.

    1. The last ice age, 10,000 years ago, pushed a lot of sand and dirt southwards, creating Staten Island, Long Island, Block Island, Martha's Vineyard, Nantucket, as well as Cape Cod and most of eastern New Jersey.
      maybe the next one will wipe them all away.

    2. The reason there are tall buildings on Manhattan Island is because the bedrock is schist and because the bedrock rises to be very close to the surface. Schist outcroppings are in many places.

    3. 12,800 years is the cycle and the next one isn't that far away.

  12. Yep, roadcuts are like candy for Geologists! I just passed a nice obsidian layer exposed on a cut along CA 178 E/O Shoshone outside Death Valley. My last visit was 1983!

  13. There's a rock near me where you can piss into the Mississippi, St. Lawrence Seaway, and Hudson Bay at the same time (after a bit of travel time)...
