The Kame-Jforalne at Jlochester, X. Y. — FairchiUJ. 49 
sand and gravel forming part of the moraine. As indicated 
upon the map, the northernmost mound of the area is a dis- 
tinct kame, over one-fourth of a mile long, lying in east and 
west direction, or parallel with tire moraine, and consisting 
chiefly of fine gravel. It lies about one and one-half miles 
nortli of the moraine. Between this kame and the moraine 
and forming part of the latter are a series of low gravel and 
sand mounds, which make a connected series and grade in 
material from the gravel of the northern mound to fine sand 
at the moraine. 
(3). lied Creek Sand Knolls. — Lying one to three miles 
south of the western end of the Rochester kame-moraine is a 
series of scattered low mounds of fine sand. The southeastern 
corner of Grenesee Valley park forms part of this sand area 
which is there exposed by the Lehigh Valley and the Erie 
railroads. Other somewhat consi^icuous mounds, ten to 
twenty feet high, occur along the road leading to West Hen- 
rietta, and the farthest lie across and below the West Shore 
railroad west of Red Creek Junction. The map shows only 
the northern part of this area. 
(4). The Brighton Sand Knolls. — These are indicated upon 
the map, lying north and east of Brighton village, between 
the east end of the Pinnacle range and the Irondequoit exca- 
vation. These are a part of the eastv/ard extension of the 
moraine, which from Brighton trends southeast, indicating 
the natural lobing of the ice-front in the deep excavation of 
the Irondequoit valley. 
(5). The Irondequoit Kame Area. — Extending from the 
head of the deeper part of the Irondequoit valley up the shal- 
lower valley, or southward, for ten miles, is a kame series of 
great proportions. It represents the drainage deposits from 
the Irondequoit lobe of the Ontario glacier, and probably far 
exceeds in quantity the Pinnacle hills. The nortiiernmost hill 
is just reached by the map. The series extends east of south 
from Allen Creek past Pittsford, ten miles, to Victor. It has 
been described in the article by Dr. Dr3'er referred to in the 
introduction of this paper. 
(6). The Mendon Hills Kame Area. — 'J'he largest and most 
interesting of the kame-like sand and gravel deposits of tiie 
region are tlie Mendon hills in the soutliern part of Monroe
