Desc. — - A series of precipitous outliers of Cape Flattery, typified by 

 Fuca's Pillar, which stands out as sharp-cut and awful as the leaning tower 

 of Pisa. The rocks lying further out are for the most part worn down below 

 the point of safe nesting; but the Pillar proper and its immediate neighbors, 

 together with the adjacent cliffs of the mainland, present unexampled 

 facilities for nesting, being hollowed out by wind action into a perfect 

 honeycomb of recesses and countersunk ledges.
