I should be writing about the fairyland that the wild blooming bluebells have made of “the island,” but it’s just too cold. Instead, let’s talk about geology.
Referring to my copy of Roadside Geology of Maryland, Delaware, and Washington, D.C. by John Means (Mountain Press Publishing Company, 2010), I can tell you that the Monocacy River, which drains most of the Frederick Valley, is situated on Cambrian Frederick Limestone as it flows through the city and its immediate environs. As I walk with my sons along the river’s shores, sometimes under tall embankments created by years of flooding, we pick up lots of quartz and limestone. My oldest son has become skilled at skipping the flatter pieces, even managing to eke out 5-7 jumps from large 5-pounders. Over the weekend we veered off our usual path and stopped at some very striking limestone formations that jutted out about 15 feet over the water. While my son found huge rocks to roll into the river – the splash was marvelous from such a drop – I found a McDonald’s cup. I hope it was iced tea that I dumped out of it.
