The Burn of Elsick flows under the Causey Mounth, an ancient drovers road dating from circa 1100 AD,[2] which track is extant as a hiking footpath.
The Causey Mounth was built on high ground to make it passable and was the only available medieval route from coastal points south to Aberdeen.
[2] The route was that taken by William Keith, 7th Earl Marischal and the Marquess of Montrose when they led a Covenanter army of 9000 men in the first battle of the Civil War in 1639.
The historic Gillybrands coaching inn and present day farm is situated on the banks of the Burn of Elsick.
[4] In Victorian times the local area was a prolific source of salmon, but overfishing to serve the expanding human population has severely reduced the fishing stocks.
