Bedrock Type

SWI2-Map ESW Bedrock

Map of bedrock reproduced from Appendix 1 on page 158 of “Exploring Stone Walls.” There’s an error in this map, a mass of granite in east-bay Rhode Island and adjacent southeast Massachusetts. This will be fixed when I get a chance.

 

Samples of stones from different map units shown below.

Rock-BoulderOnGraniteAcadia

Map unit “Granite & Gneiss” (PURPLE): generally  massive and uniform, giving rise to ball-shaped boulders.

Stone-ShapeSlabTablet

Map Unit ‘Schist & Quartzite’ (WHITE): generally giving rise to well-layered and resistant tablets and slabs). Cobblestone provides the contrast.

Stone-FaceRedbedSomers

Map unit ‘Soft Rock” (YELLOW): generally non-metamorphosed sandstone and limestone/marble. These are usually easily crushed, making walls rare.
