LOCAL GLACIATION IN CATSKILL MOUNTAINS 115 



Lawrence valleys." He has shown^ that the moraine described by 

 Agassiz, to which reference has already been made, is a part of a 

 morainic belt encircling the White Mountains, and was formed at the 

 margin of the local ice-cap which once covered them. At a later stage 

 small local glaciers persisted in the mountain valleys. 



Fig. I. — ^View of a lake and its inclosing moraine built by a local glacier which 

 descended from one of the higher ranges of the Catskills. This photograph was 

 taken from the steep mountain valley down which the ice moved. In the foreground 

 is a hummocky deposit representing later stands of the ice. 



In the Adirondacks, Gushing^ mentions evidence of the exist- 

 ence of valley glaciers either during or shortly after the retreat of 

 the ice. Tarr, to whom I am indebted for references and helpful sug- 

 gestions in the preparation of this paper, informs me that the Ausable 

 lakes show evidences of having been formed by deposits from valley 

 glaciers.
