An important feature of the quarry site is a group of large granite 

 bowlders called the maidens (fig. 134), brought from the far north 

 by glacial ice, about the base of which, engraved on the glaciated 

 floor of reddish quartizite, were formerly a number of petroglyphs, 

 representing no doubt mythological IxMngs associated with the lo- 

 cality. Additional interest attaches to the locality on account of an 

 inscri])tion left by the Nicollet exploring jiarty in 183S. The nauie 

 of Nicollet and the initials of five other persons, including those of 

 John C. Fremont (C F. only) are cut in the flinty <iuartzite rock 

 face near the "leaping i-ock " at the falls. 



The principal explorers of the site are Nicollet, Catlin, Ilayden, 

 Winchell, and the writer.
