March’s County Geological Site for Geological Survey Ireland, DECC is the Temple Bar Street Well, Dublin.

This hydrological feature is thought to date from between 1680 to 1720 and was significant to the development of Dublin as it supplied freshwater to local residents.

Happy St Valentine’s Day from Geological Survey Ireland, DECC. Love hearts can even be seen in our landscape, such as the heart shaped, glacial lake Lough Ouler in the Wicklow Mountains.
The glacial lake (tarn) formed when a glacier melted & retreated filling a corrie with water. 💚💚💚

January’s county geological site is Dunmore Cave, Co Kilkenny.
⚫️🟡

The cave formed when glacial meltwater (last 2.6 million years) chemically dissolved the permeable Carboniferous limestone (359 – 323 million years old) and resulted in impressive stalactites and stalactites.
