LAKE IS A CHERISHED MEMORY

scientists left little to be done by
their successors save few points OF
detail. During the same year, under
date of May %, a federal law re-
served the territory of which Crater
lake is theicenter as a national park,
having an area of 645 square kilo-
meters. Finally, in 1908, a party of
topographers began a new survey of
the lake and the surrounding terri
tory, including the entire park.
Their work resulted in a publication
of topographic sheet on scale of
1 to 62,500, issued by the geological
survey in 1911. This map of rigor
GUS exactitude was of great service to
us in our visit to Crater lake.
Here are some of the more impor-
tant facts concerning the crater it.
self and the lake which it embraces:
The greatest diameter in an east and
west direction, measured from shore
to shore from the foot of The Watch
man to Redoloud cliff, is about $500
meters; the smallest diameter, fol-
wing a direction almost at right
angles to the above, from Pumice
point to Eagle point, is $500 meters.
The circumference is approximately
80 kilometers, although to make the
tour of the rim on foot would make
the actual distance Sc kilometers.
The water, shallow in the western
part, where an island of cinders and
scoria, Wizard island (2,114 meters
above sea leveD, rises 232 meters
above the surface of the lake, is else
where very deep, the bottom sloping
rapidly downward. The greatest
depth noted in the eastern part, op-
posite Skull Head, is not less than
COS meters. This depth, which is
almost identical with the measure
ment of the highest point of the rim,
Glacier peak, which rises 603 meters
above the surface of the lake, gives
a total depth of 1,211 meters for
this enormous crater. The bottom
of the crater is, therefore, 1,274 me-
ters above sea level.
The interior slopes or walls of the
crater, parts of which are wooded,
are extremely steep, and rise almost
everywhere as unbroken cliffs, maxi
ing it almost impossible for one to
get a foothold. However, one may
reach the waters edge quite easily
by following zigzag path which
leads from Crater Lake Lodge to
Eagle cove, where tourists may find
during the summer season a small
gasoline launch and several row.
