I passed the spot a few weeks ago on the bike and was pleased to see the spot is now marked. If you find yourself down that way be sure to stop and thank those pioneers for setting a flame that still burns.
The monument reads:
Here burned the Craigallian Fire. During the Depression of the 1930s, it was a beacon of companionship and hope for young unemployed people who came from Glasgow and Clydebank seeking adventure in Scotland's wild places. Their pioneering spirit helped to make the Scottish countryside free for all to roam.
