A Form of Outwasfi Drift 
53 
that the degree of development of this drift-form varies with the 
time the ice stands at a given halt. 
Woodworth alludes^ to a washed drift which confronts the 
terminal moraine on Long Island; this formation, as described, is 
a normal outwash plain. 
In his description of the drift in southern Wisconsin, Alden* 
describes an ^‘outwash apron’’ which constitutes a portion of the 
deposits in the interlobate angle between the Lake Michigan 
Glacier and the Delavan lobe; his usage of the term outwash else- 
where in the paper is also in accord with the standard of definition. 
In applying this definition to the localization of drift referred 
to on the north slope of Bluff Point, we note the following facts: 
(l) the absence of an initial plain, (2) the probable absence of a 
strong sub-glacial stream, (3) a constancy in the position of adja- 
ent ice-lobes which built up lateral moraines, (4) a synchronous 
accumulation of debris at the reentrant ice-angle, (5) diverging 
slopes to the south that insured rather active drainage away from 
this angle, and (6) a single alluvial fan-like body of washed drift 
blending northward into moraine. 
The normal outwash plain is an assemblage of such alluvial 
fan-like units. The drift in question is quite identical with an out- 
wash plain in structure, but different from it in degree of develop- 
ment and in topographic environment; ignoring the latter discrep- 
ancy, we may say it is a very subdued form of outwash plain that 
represents a constant position of the ice at the junction of two 
rather small valley dependencies. 
Since Bluff Point is a not uncommon type of topography in the 
Finger Lake region, and since the writer has mapped on the 
Moravia quadrangle similar deposits of drift, he suggests, as a 
designation for such deposits, the term inter-lohule (or inter-tongue) 
fan.
