North Twin is one of the two main peaks that comprise The Twins massif located at the northeast corner of the Columbia Icefield in Jasper National Park, Alberta, Canada. The other lower peak is named South Twin. North Twin is the third-highest peak in the Canadian Rockies, after Mount Robson and Mount Columbia.
The massif was named The Twins in 1898 by J. Norman Collie and Hugh M. Stutfield. The decision to name the peaks separately was approved February 28, 1980.
In addition to North Twin and South Twin, the massif contains a northern subpeak of North Twin known as Twins Tower, 3,627 m. This sits atop the famed north face of the massif, and was named in 1984. Further, another subpeak in the massif is known as West Twin 3,360 m, a picture of which can be found in the South Twin Gallery - access to this peak is from the North/South col.
