“Some drill and bore
The solid earth, and from the strata there,
Extract a register, by which we learn
That He who made it, and revealed (!) its date
To Moses, was mistaken in its age.”[60]
The following is a list of the principal orographic features, Jökulls,[61] Fells (mountains), volcanoes, masses of Palagonite, snow-peaks, and true glaciers, which are rare. Gunnlaugsson’s astronomical positions are given in Danish feet, and the former are reduced to the meridian of Greenwich by assuming Copenhagen to lie east 12° 34´ (Rafn, 12° 34´·7). The Danish foot is calculated at 12·356 inches English, or about 67:69.
The north-eastern quarter numbers fifteen points, ranging from 1000 to 3000 Danish feet, and the following ten exceed the latter:
