Yoga in Harpenden Common - SG1

Nomansland Common is an area of common land in Hertfordshire, England to the south of Harpenden and the south-west of Wheathampstead Geologically, the common is part of the Harpenden Dry Valley. In the last ice age a glacier dammed the river south of Sandridge into St Albans Vale, creating a lake. When the dam melted and water drained away, it left the thin, stony soil still found on the common today. Wikipedia
