Soon after you leave the shelter of the trees you come to a mountain tarn .
A classic glacial relic, the tarn lies in a trough that was cut by ice moving across from Great to Little Langdale.
A bridge crosses the point where a small beck that catches water from Iron Keld and Black Crag brings the main supply of water to the tarn .
All around it is limestone, which anyone who has studied geography at school will know is pervious and water disappears through it, the area of the tarn lays on Silurian Slate, hence the reason for this magnificent sheet of water.
After passing the Dollar Lakes, I hear the gurgle of a stream and then see Lamoille Lake, a shallow mountain tarn in a glacial bowl, with steep talus slopes cradling it.
The climb continues easy and steady on track in a small, closed-in valley, so there is only close-quarter interest: another bridge, a waterfall, lesser ruins, then a pretty tarn .
The region is packed with hundreds of bodies of water, relics of the last ice age, 10,000 years ago, but most are deemed too small to be called lakes, and are referred to locally in the old Norse word, tarns .
A spectacular six-foot dragonfly will also be installed on one of the tarns in the forest just another addition to the 90 permanent sculptures on show every year.
From the top of the ridge you can see a number of mountain tarns and look down into the Wairau Valley on the other side.
Coots, ducks and flamingos clustered around the fringes of shallow tarns whilst great flocks of upland geese, buff-necked ibis and lapwing settled on the plains to feed.
