Loss
of Resources
Geoantiquities
values, as long- term scientific and cultural resources, suffer in favor
of economically attractive short-term options with lasting con- sequences.
Geoantiquities assets are liquidated by: |
Removal (Fig. 6)
Burial
Mutilation
Contamination
Multiple Impacts

7. A. Engraving "Fault scarp crossing alluvial cone, near Salt Lake City",
drawn by W. H. Holmes, Plate XLIV, p. 348 in Gilbert (1890). This geoantiquity
illustrates Lake Bonneville shoreline deposits, alluvial fan develop-
ment, and fault displacement. B. The fan has since been entirely removed
for the sand and gravel resource. The site is now an industrial area in
Salt Lake City, Utah. |
Fig. 8. Two years of change
in Gilbert delta exposures at the mouth of Big Cottonwood Canyon, Salt
Lake City, Utah: A. 1993 view (top) of large Provo-level delta foresets,
dipping to the west, where sand and gravel was actively quarried. B. 1994
view (bottom) of the same site, where the delta foresets were remolded
and regraded for con- version to a county golf course. Presently the area
is covered with manicured grass, and houses are rapidly building up along
the available shorelines just behind and overlooking the golf course.

Fig. 9. Competing uses of the Point of
the Mountain spit, at the south end of the Salt Lake Valley. A. This
geoantiquity is a world class paragliding/hangliding area, that is being
pushed out by new housing development (left) which will soon cover this
whole shoreline bench. Growth is so rapid, that this site is almost
a stone's thrown from the Utah State Prison (formerly put outside the
populated areas, but now literally in the center of suburbia). B. The
south side of the Point of the Mountain is being rapidly removed by
sand and gravel quarrying. Tons of gravel are hauled off by railway.

| Fig. 10. The Draper Spit (center) is
enveloped in housing. The only part of the spit that does not have houses
is the sandy face that is too steep to build on. |

Fig. 11. The Bonneville shoreline (bench
just below the "U" on the hill), is now obscured by expensive home construction.
