FORM OF NANTASKET BEACH 185 



beaches appear to be more or less continuous from Allerton to White- 

 head. The remaining changes indicated on the drawing need but Httle 

 comment. The removal of White Head Lost Drumlin, together with 

 the formation of the County Road Beach, has resulted in the clifhng 

 of White Head on the east and northeast, while the removal of the 

 Atlantic Lost Drumlin has allowed the connecting bars to swing back 

 and form a single bar which unites with the rock cliffs at Atlantic 

 Head. 



The next stage in the development of Nantasket Beach is that of 

 the present, represented in Fig. 8. The principal change from the 

 preceding stage consists in the prograding of the beach until it makes 

 an unbroken, gently curved shoreline from Great Hill to iVtlantic 

 Head; the further clifhng of White Head at the eastern end and the 

 abandoning of the cliffs on White Head and Sagamore Head by the 

 waves as the shoreline migrated eastward; the complete removal of 

 the Skull Head drumlin, partly within recent years; the filhng-in of 

 the smaU bay on the south side of Windmill Point, largely within 

 historic times; and further erosion of all the drumlins still exposed 

 to wave action. 



In Fig. 9 we have attempted to represent a possible future stage 

 in the development of Nantasket Beach. At the present time the 

 most effective wave erosion is concentrated upon Great Hill and the 

 small remnant of Little Hill. But these hills control the future of the 

 beach, the erosion of the rocky mainland at the southern end being 

 so slow as to be practically negligible. Heretofore the retrograding 

 of these hills has caused the prograding of the beach; at the present 

 time, however, a condition of equilibrium prevails, and a further 

 cutting-back of the hills must result in a cutting of the beach also. 

 With Great Hill gone, the beach would connect Nantasket Hill, 

 Little Hog Island, Strawberry Hill, White Head, and Sagamore Head. 

 Strawberry Hill would be at an exposed angle of this beach and would 

 soon be destroyed. Little Hog Island and White Head would be 

 more exposed than before, providing the former had outlasted Straw- 

 berry Hill. Sagamore Head and Hampton Hill would take their 

 turns in controlling the position of the beach until completely reduced 

 by the wave attack. The drumloidal extensions west of White Head 

 and the Hull district at the north will be the last remnants of Nan-
