Baltimore's Geology - with Martin Schmidt

Martin Schmidt, author of Maryland's Geology, offers this workshop as an overview of the geology of Baltimore--the landforms, the underlying rocks and their structure, and a bit on the long history that put it all together.   

Geology in the Baltimore area is fairly complex because it results from a billion years of geologic activity.  While this makes it a bit complicated to explain, it's a great opportunity to learn about a variety of processes.  And though the rocks are mostly covered by soil, they frequently have a direct effect on our choices and actions as we travel and live in this area.  This talk will discuss the geology of the Baltimore metro area and some of its effects.  Please let us know where you live (such as town or neighborhood) by answering the question when you RSVP, so we can attempt to include your area in the discussion.



This talk builds on the one about the State's geology that Martin offered in the spring, but you don't need to have attended that talk in order to attend this one.

PLEASE NOTE Cost:  $25 for non-members; $10 for members

Martin Schmidt has been teaching grades 9-12 at McDonogh School since 1978, including physics, chemistry, and geosciences over the years.  He currently teaches an Honors Geology course to 12th graders, which also earns students credits from Towson University. 

His book, Maryland's Geology (Schiffer Publishers), is designed to give a basic geologic background and then apply it to the state, for students, teachers, and laypeople.

    Terrific! Especially appreciate the insight into the significance and context of rock classes. Here's the link to MD Geology for Education resource that Martin shared.

    I was very sorry to have missed what must have been an interesting lecture. Was under the weather. I'd love to know whether Mr. Schmidt will be speaking again some time.

    Martin's presentation was Goldilocks Geology--just the right about of fascinating and relevant info on a very complicated topic.

    I am sorry to miss this as well, since I'll be at an event for our neighborhood in Leakin Park.

    Has Martin seen the rocks excavated from the Robinson Nature Center and can he describe their provenance.
