Just a heads-up for DC-area readers: The spring 'edition' of Walkingtown, DC is coming up, and once again I'll be leading my "History Before History" tour. This three-hour walking tour of Adams-Morgan, the Zoo, and Rock Creek Park covers the geologic saga which formed the bedrock of the nation's capital city. We'll look at the Rock Creek Shear Zone, Cretaceous-aged river gravels, a faulted unconformity, and the Georgetown Intrusive Suite. It's free and open to the public. More information is on the Walkingtown website. Please join us!
