Glenariff is a valley of County Antrim, Northern Ireland. Known for lush farmland, this glacially carved glen has a mouth on the North Channel of the Irish Sea at the town of Waterfoot. Here is the view from the Glenariff Forest Park. The foreground white flowering bush of pinnate leaves is Rowan (Sorbus in the family Rosaceae subfamily Maloideae). In Irish it is Crann Caorthainn, a plant considered sacred in ancient times by both Celts and Vikings. The fruit is made into preserves, jellies. The pinnate leaves are similar to Ash, the reason it is also known as Mountain Ash, Rowan is botanically unrelated to Ash.
