An island in the Sea of Rhûn?

[ZehnWaters]

I'm looking over the map as drawn by JRR Tolkien and rerendered by Christopher and there's...something in the middle of the sea of Rhûn. Does anyone know what it is?

I've often wondered about this, as well.

The Tolkien Gateway has a little info about the island in the Sea of Rhun:

The south-eastern part of the Sea seems to be occupied by a small wooded island.[4][5][6]

In the earlier maps, part of the Sea was more clearly occupied by a heavily wooded island.[12] In the published maps by Christopher Tolkien, the island is represented by a dotted pattern.[14] The reason for this change and what it signifies was never specified by C. Tolkien.

6. J.R.R. Tolkien, Christopher Tolkien (ed.), The Treason of Isengard, "XV. The First Map of The Lord of the Rings", "Map II", Map II, The island in the Sea is coloured green on the First Map, and is marked as wooded on the 1943 Map, p. 307

I thought there was a wooded isle in the Sea of Rhun, but the 'dotty' symbols that replaced the woods looked more like it was a swamp ala Midgewater. There was thick woods to the northwest of the Sea of Rhun. Maybe the island was logged?

It looks like it's coloured the same colour as the woods in this first map. BUT Tolkien heavily revised things from this map.
