ource of infor- 
The unconsolidated sediment of the upper ridge portions 
proved to be unfavourable for supporting a permanent vegetation cover. 
Consequently the upper part of the ridge surface remained barren 
yielding a lighter tone quality due to unvegetated sandy, silty 
material which provided a conspicuous contrast with the surroundings.

Il choisit au hasard sur le terrain quatre stations différentes 
présentant des escarpements. Ceux-ci furent identifiés sur photos 
aériennes et on prit note des dimensions du sol soulevé, du substrat, 
de la nature et du type de végétation. 
Les sédiments non consolidés sur le dessus des côtes suppor 
taient mal une végétation permanente. Par conséquent, ils restaient 
nus et leur teinte sur les photos était plus pâle vu qu’ils étaient 
formés de matériaux sableux et limoneux contrastant fortement avec le 
paysage environnant.
