BALTA, an islet (small), in the parish of Unst, county
of Shetland. This is nearly the northernmost isle of
the Shetland range. It is situated in the latitude of
60° 4*' north, and on the east side of Unst island, the
sea between being called Balta Sound. Here the shore
of Unst forms a fine and safe inland harbour, stretching
east to west about two miles, protected at its mouth by
the isle of Balta.
