Estolîn

Estolin (S. “Peaceful Lake") the great lake near Barad Tathren.It had been named by Eariel o Tatharim when she ﬁrst saw it and the name had remained in use ever since. The lake was divided by a ﬂat promontory for most of the year and was about l miles long and just over mile wide. In winter it freezed over for several months, being for the most part very shallow and the Castle's inhabitants enjoyed skating across its glassy surface. There were not great numbers of ﬁsh, but enough to support a good population of birds and other creatures both in the lake and around its shores, such as otters and harriers. The deepest channel in the lake joined the two streams from the marshes at its north and south ends, running down the eastem side of the lake past the castle through the marsh and the willow thickets.ln the middle of the northem half of Estolin lay Tol Farenir (S. “Harriers Island")
