today seen at least 7 different sets of mole
"ridges"--which are here only lines of cracked
earth; that is, a slight raising of the wet,
packed surface merely fractures it. No wonder
one can see no sign of moles when the
sand and gravel is dry and loose. It would
appear that the "rare" San Pedro Martir mole
is not so rare, after all. Only one must
look for it just after a rain.
