Rescue teams have been stood down following the search for a woman in difficulty at the Den of Finella beauty spot north of St Cyrus.
Emergency services, including HM Coastguard, were called to the scene at around 2pm.
It is understood she slipped at the area beside the waterfall and got into difficulty in the water.
A major water rescue operation was launched with coastguard teams, police, firefighters and paramedics all scrambled to the scene.
The A92 in Kincardineshire was also closed to allow emergency services access to the scene.
Crews remained at the scene for more than four hours as search efforts got underway.
The operation has since been stood down for the evening.

In a statement, a Police Scotland spokesperson said: “Around 2pm on Sunday we received a report of a woman in the water near the Den Finella Waterfall, St Cyrus.

Den of Finella
The Den of Finella is described as a scenic spot steeped in myth and legend.
White water roars 70ft down a sheer ravine, through a green canopy and into a series of plunge pools.
Den Finella’s waterfall is known as the “lost waterfall of Scotland.”
Shrouded in folklore and mystery, the den is named after noblewoman-turned assassin Finella, who supposedly leapt to her death here in 995.
