Mount Estella is a 3,069-metre (10,069-foot) mountain in Alberta, Canada. It sits in Jasper National Park and is the second-highest peak in the Trident Range of the Canadian Rockies. The town of Jasper lies about 16 kilometres to the northeast, and the Continental Divide is about 11 kilometres to the west. The nearest higher peak is Majestic Mountain, roughly 1.08 kilometres to the south.

Description
Mount Estella is part of the Canadian Rockies. It receives runoff on its east slope into Portal Creek and the Athabasca River, and on its west slope into the Miette River. The summit rises about 1,100 metres (3,600 feet) above Circus Valley in about 2 kilometres, giving it steep relief.

History
The mountain’s name first appeared around 1916–1917, likely named by Dominion Land Surveyor Morrison P. Bridgland, though the exact origin isn’t recorded. The name was in use by 1917 and was officially adopted in 1951. The first ascent was made in 1930 by Newman Diefendorf Waffl. He later died that same year on Mount Robson.

Geology
Mount Estella is made of sedimentary rock laid down from the Cambrian to Jurassic periods. These rocks were pushed eastward over younger rocks during the Laramide orogeny, and the strata on the peak are tilted to near-vertical.

Climate
The area has a subarctic climate with cold, snowy winters and mild summers. Winter temperatures can drop below -20°C, with wind chill well under -30°C.
