65 million years ago
Eyjafjallajökull volcano in Iceland was formed around 700,000 years ago and last erupted in 2010.
Worldwiode, many tens, perhaps a few hundred, of millions of years - as long as there have been karst uplands. Many that formed in that time no longer exist because the landscapes in which they developed have long been eroded away.
The Taconic Mountains were uplifted approximately 440 million years ago during the Ordovician period.
... I know this might no be very use full but, so farr rings have shown over 2 million years ago but thats only when it stared it continues to change and errode due to wind and offen flooding.
As of this writing, it's 2012 CE. You can subtract to find the answer.
In simple terms, about 60 million years ago volcanic activity forced lava onto that area. The drying lava caused the solidifying lava to crack and form regular pillars of basalt rock, which we see today.
No, there are no volcanoes in Ireland now. But at one time, a long time ago, there must have been because the Giant's Causeway in Northern Ireland was formed by a volcano.

The Giant's Causeway in Ireland is primarily made of basalt columns, which were formed by volcanic activity millions of years ago. The distinctive hexagonal shapes of the columns were created as the lava cooled and fractured.
The Giant's Causeway was formed around 50-60 million years ago during a series of volcanic eruptions. The unique rock formations were created as lava cooled and contracted, resulting in the distinct hexagonal columns we see today.
The Giant's Causeway is a natural landform consisting of approximately 40,000 interlocking basalt columns, formed by volcanic activity around 60 million years ago. Located on the northeast coast of Northern Ireland, it is characterized by its unique hexagonal shapes and is a UNESCO World Heritage Site. The columns were created when lava cooled and contracted, resulting in the distinctive geometric formations that attract visitors.
They were formed on 23rd July 2010.
the giant's causeway is a bundle of rocks in Ireland formed by erupting volcanoes The Giant's causeway is an area of about 40,000 interlocking basalt pillars. It is located off the North East coast of Ireland. The Giant's Causeway was named the 4th wonder in the United Kingdom. The formation was the result of a volcanic eruption. Each Pillar is of a hexagonal shape, and the form steps all up and down along the land mass. It really is a puzzling sight. For Pictures and more info see the link below.
