Trust Wyman Meinzer to see as no one ever has the desert sanctuaries of the vast Big Bend and to pay tribute to their best-kept secret, the twin canyons of the Chinati Mountains, San Antonio and Los Pelos. Trust, too, that the images he delivers are as true as his eye, that the light bathing cholla at sunrise, on the eastern rim of San Antonio Canyon, is unfiltered. Meinzer is one photographer who still waits for and catches the light, even if he has only a thirty-second window.
