deep valley. This mountain they concluded from Coleman's report was an 
unnamed mountain; this they later called Mt. Pease, 
The fleeting glimpse of this high moutnain, together with the very 
interesting plants collected in the few hours on the one day th&y had 
in the region resulted in Pernald and Pease organizing a botanical 
expedition to this region in July, 1923. 1 was a member of this partji, 
and this is the trip that I shall tell you sorathing abut at this time. 
The other members of the party were Prof. Pernald of Harvard (in charge). 
Prof. Pease of the Univ. of Illinois, Dr. Dodge of Harvard (who was 
^ Tv-C- /CP {A- ■ 
presddent^of the K.-1. g.iJ.C-. inl921), Mr. Mackenzie and Mr. Griscom of 
New York O^ty (the latter assistant curator of birds in the Amer. Mus. 
of Nat. Hist.), and Mr. Smith, a Harvard student. Each member of the 
party was assigned(as their speciality certain general types of work; 
my own was photography, map making, and the collection of parasitic 
fungi and mosses. 
Briefly stated, the trip resulted geographically (1) in securing 
l 
conclusive evidence that Coleman's "Mt. Logan" was an unnamed mountain 
which, notwithstanding my protest, the leaders of our 1923 trip insisted 
on calling Mt. Collins, because 1 happened to have done c^eedrderarcrfce 
exploring on it; (2) that the high mountain 4 or 5 miles to the eastward, 
called Mt. Pease in 1922, was the real Mt. Logan: and (3) that beyond 
Mt. Logan was a tceraendous cirque-like basin with walls about 1000 ft. 
high (apparently containing one or two patches of perpetual snow),the 
existance e- f wh i ch seems not to have been known to anybody, so far as 
we could learn at the time or later. This hatsxn we A called Pease Basin, 
- p, v 
after Prof. Pease wno did most of the explora44-e» in it. 
Logan's description of the mountain, as originally published, which 
\ 
Coleman said was vague and erroneous, is nolr/perfectly clear to us, and 
accurate, too. To Coleman, however, who had wrongly identified the
