I was given the chance to take a tour of this incredible private estate. The resident wanted to learn more about the rock outcrops that are located there. It was fascinating! All of the rock outcrops are igneous, but they are tremendously altered by numerous inclusions, veins, and dikes of quartz and basalt. It was quite an experience. -Charles F. Lindgren

It is expressed as the ratio of the average radius of curvature of the edges or corners to the radius of curvature of the maximum inscribed sphere. The sphericity of a particle is: the ratio of the surface area of a sphere (with the same volume as the given particle) to the surface area of the particle.

	The most common geologic characteristic at The Glades is the interaction between Granite and Basalt. In all cases the granite formed first, and then the basalt created dikes in the Granite. In some cases the dikes have feldspar or quartz crystals in them. (Note: Toes are included for scale)	Then there is this unusual mixture of Granite and Basalt!



This one outcrop had an unusual alignment of lines that I assume are glacial striations.	Who's a good girl? One of my tour guides' dogs!	Then there's the dead seal.



My favorite dike image! I wish I was still teaching!		Incredible Tide Pool! There was algae, and crabs, and mussels and . . .
