A horse in Urkulu Mountain.
Urkulu is an iconic mountain in the Basque Country straddling France and Spain. The summit is located in the western Pyrenees, within walking distance from Roncevaux and close to the branch of the Way of St James crossing the mountain range at the historic pass.
The main feature of the mountain lies on the remains of the tower topping the summit, dating from the Roman times and apparently erected to celebrate the conquest of Aquitaine. However, with the summit providing an excellent view over the northern and southern slopes alike, it was used as a watchtower in Medieval and Modern times.

A thesis about the origin of the Garonne holds that the river rises on the slopes of Pic Aneto, at 2,300 m a.s.l. and flows by way of a sink hole known as the Forau de Aigualluts (42º40′00″N 0º40′01″E) through the limestone of the Tuca Blanca de Pomero and a resurgence in the Val dera Artiga above the Aran Valley in the Spanish Pyrenees. This underground route was suggested by the geologist Ramond de Carbonnieres in 1787, but there was no confirmation until 1931, when caver Norbert Casteret poured fluorescein dye into the flow and noted its emergence a few hours later 4 kilometres (2.5 mi) away at Uelhs deth Joeu (“Jove’s eyes” 42º40′51″N 0º42′28″E) in the Artiga de Lin on the other side of the mountain. From Aigualluts to the confluence with the main river at the bed of the upper Garonne valley (800 m a.s.l.), the Joeu has run for 12.4 km (16 more to get to the French border), carrying 2.16 m3/s. of water, while the main river is carrying 17.7 m3/s.

The Canadian Rockies comprise the Canadian segment of the North American Rocky Mountains range. They are the eastern part of the Canadian Cordillera, extending from the Interior Plains of Alberta to the Rocky Mountain Trench of British Columbia. The southern end borders Idaho and Montana of the USA. The northern end is at the Liard River in northern British Columbia.
The Canadian Rockies have numerous high peaks and ranges, such as Mount Robson (3,954 m (12,972 ft)) and Mount Columbia (3,747 m (12,293 ft)). The Canadian Rockies are composed of shale and limestone. Much of the range is protected by parks and a World Heritage Site.
