Friends:

    I've just come across a book that might be of interest to those
of you in western N. America--

    Webb, Robert H. GRAND CANYON--A CENTURY OF CHANGE. Univ . of
    Ariona Press, Tucson. 1996.

    Fascinating comparative rephotography, plus treatment of
vegetation dynamics (e.g. Ferocactus cylindraceus vs. Encelia
farinosa, p. 88).
