Wetherlam stands apart from the main north–south spine of the Coniston Fells, the connection being via the long east ridge of
Swirl How. Midway along this ridge is
Black Sails, an intermediate top usually considered to be part of Wetherlam, and listed as a
Hewitt in its own right. From Swirl How the east ridge drops steeply down Prison Band to Swirl Hawse, before rising again to the summit of Black Sails. Black Sails has a descending southern spur which steps down over High and Low Wether Crags. Between this and the main Coniston range is the valley of Swirl Hawse Beck and
Levers Water. This
tarn has been raised by damming to a depth of , originally to supply water to the Coniston Copper Mines. Following the decline of mining a water treatment plant was built, and since the 1970s the tarn has supplied drinking water for Coniston and other local villages as far east as Sawrey. The main ridge continues east from Black Sails across the depression of Red Dell Head to the summit of Wetherlam. A second southward spur, paralleling that from Black Sails, descends from the main summit. This is Lad Stones ridge and the valley contained between the two is Red Dell. Wetherlam has a further ridge which descends steeply north eastward along Wetherlam Edge. This leads via Birk Fell to an attractive upland plateau between Tilberthwaite and Little Langdale. Many rocky knolls characterise the area, the most prominent being Blake Rigg and Great Intake. To the south east of Wetherlam is a further upland area, named Yewdale Fells on
Ordnance Survey maps. This displays less bare rock, but is fringed by a wall of crag above the
Coniston -
Ambleside road. To the north of Wetherlam is the Greenburn Valley, a feeder of Little Langdale. A steep sided, rather marshy valley, Greenburn's waters join the River Brathay at Little Langdale Tarn. Greenburn itself bears a tarn, or more correctly the remains of a reservoir. A natural waterbody was dammed in the early 18th century to provide water for the Greenburn Mine. The barrage has now been breached to leave a collection of pools and bogs. Greenburn is bounded to the north by the curve of Wet Side Edge, falling from
Great Carrs. ==Summit==
