Stormy weather. We went for a short walk between two rain showers and got this beautiful light.
Have a nice Sunday evening.

[as a geologist and an adventure rider – and a Colorado resident that loves history - I have travelled all over this area; first photo is mine, my motorcycle under the Apishapa Arch in Aguilar, Colorado, a 1930s Civilian Conservation Corps project through a volcanic dyke, ‘coincidentally’ providing better access to land that a senator had purchased up around Cuchara and Cordova Passes]

Above and upon #igneous #dikes
The feature sure looked like a #dike on #satellite view, and a ground check confirmed it. Probably a late #Triassic or early #Jurassic intrusion into #Proterozoic Dedham #Granite, as #Pangea rifted. At Black Rock #Beach, #Hingham, #Massachusetts, #NewEngland #geology USA.
