The Jerall Mountains are the highest mountains in the Province of Cyrodiil, and straddle most of the northern border. The province of Skyrim lies on other side of the range. This is generally Nord territory.
The Valus Mountains are a particularly rugged section of the province. The weather is often snowy and visibility is poor. The region is lightly forested with evergreen trees, and hardscrabble brown grass grows year-round. As the range slopes south, however, it becomes more mild and green grasses and deciduous trees can be found in the foothills leading to the Nibenay Basin.
West Weald is a sunny, lightly-forested region occupying a crescent-shaped arc southwest of the Imperial City, acting as the northern border for the provinces of Elsweyr and Valenwood. This verdant region is notable for its wide-open and purple-flowered meadows, distinctive red maple trees and rich agriculture.
