Laysan - area: ^23 acres 
(Calculated by Warner, ms. ca. 1958 
using results of Tanager expedition 
and including lagoon area. This equals 
ca. 1.43 square miles. Bryan ( 195 ^) 
gave the area as 1.56 square miles, 
(converts to 996 acres) 
Dill and Bryan, I912 basing information on I902 Albatross expedition 
gives a 
total area of ca. 
land area of 
lagoon area of 
5?^20,800 square yds.

Probably Warner figures are the most accurate. 
Elevation maximum --- just over 40 feet.

ca. 450 acres (Freeman, 1951 ) If this figure is anywhere 
near correct- From tracing of I966 Photograph I get 
the following estimates:

Earlier I7 May 1943 aerial suggests 
island is much more vegetated now 
than then.

Elevata^n maximum —- do not know but Tanager expedition survey gatoe 
northwestern portion contour at 40 ' which indicates peak height 
slightly more than that. I, am not sure that I believe these firures 
kmngkx though. At present at least from my observations I would 
think that the southeastern dunes are the high point of the island 
but I personally doubt that they are, at best, more than 30 feet 
above water level. The I931 hydrographic survey gave the high 
point of the island as 20 feet in the northwestern portion of the 
island which seems much more like it. If southeastern dunes are now 
high point I think 25 feet would be an acceptable estimate of present 
maximum height. ^
