Subject category Comment text
Deposit SURFACE SLOPES NEAR THE TOP OF THE VOLCANO ARE COVERED WITH LOOSE, WHITISH-GRAY PUMICE AND ASH. THE WEST LIP OF THE CRATER IS COVERED BY LIGHT GRAY-WHITE DUNES COMPOSED OF SANDY VOLCANIC GLASS WITH MINOR QUARTZ, FELDSPAR, AND MICA. THE DUNES ARE 300 M LONG AND 100 M WIDE. DEPTH IS UNKNOWN, BUT PROBABLY APPROACHES 5 TO 10 M. NEAR THE WESTERN BASE OF VOLCAN QUEMADO IS AN OUTCROP OF LIGHT PINKISH GRAY WELDED TUFF WHICH HAS BEEN QUARRIED FOR LOCAL USE AS BUILDING STONE. THE TUFF BREAKS IN A ROUGHLY CONCHOIDAL FASHION AND APPEARS IN PLACES TO HAVE BEEN NOTICEABLY WEATHERED DESPITE ITS PRESUMABLY YOUNG AGE.
