Geo-route -Gállego River’sglacier
It may seem unbelievable, but only 35,000 years ago, the ice of a big glacier covered the whole Alto Gállego Valley almost all the way to Sabiñánigo. Afterwards, the Earth’s temperature rose and the ice disappeared, but it left many clues of its presence all along the valley. Throughout this excursion we will follow these clues while discovering the story that each of them tells us:- The valley’s U-shape.- The frontal moraine on which today stands the village of Senegüé. - The amazing Os Lucas Waterfall, vestige of a hanging valley.- The fairy chimneys in the Arás Gully, bizarre geological formations of a unique beauty made at a lateral moraine. If you want to travel into a frozen past, when big mammoths wandered very close to here, you cannot miss this visit. Estimated duration: 3-4 hoursThe duration is an estimate and only half of it would be reallymoving around; the rest would be used for explanations at the different stops along the route. Specifications: The starting point of the Gállego River’s glacier geo-route is located at the parking lot of the restaurant Casa Casbas, in the town of Senegüé.The finishing point is the same as the starting point, and it is accessible by car. Transportation to the starting point is not included as part of the activity. Important remark: Due to the distance between the different points of the geological visit, this geo-route combines car rides with walking routes. You must bring your own car, but all the parts where a vehicle is needed will be on the road.This activity is suitable for children over 8 years old and the pace of the excursion will be adjusted to them. Younger children may follow the activity if their parents or guardians believe it is suitable for them.
