Cape Thompson 



The Cape Thompson flora is richer in species and individuals 

 than that of any other point on the Arctic shores we have seen, 

 owing no doubt mainly to the better drainage of the ground 

 through the fissured frost-cracked limestone, which hereabouts 

 is the principal rock. 



Where the hill-slopes are steepest the rock frequently occurs 

 in loose, angular masses, and is entirely bare of soil. But 

 between these barren slopes there are valleys where the showiest 

 of the arctic plants bloom in rich profusion and variety, forming 

 brilliant masses of color — purple, yellow, and blue — where certain 

 species form beds of considerable size, almost to the exclusion 

 of others.
