COLORADO RIVER TRIPS WITHIN THE GRAND CANYON NATIONAL PARK AND MONUMENT: A SOCIO-ECONOMIC ANALYSISBoster, Mark Alan 06 1900 (has links)
The recreational use of the Colorado River within
the Grand Canyon National Park and National Monument
increased on the order of 60 to 70 per cent during each
year of the interval 1967 to 1970. Consequently, the U. S.
National Park Service instituted user limits to protect
and preserve the area commencing with the 1971 season.
This limit was established with limited data on the users
of the river or about their perceptions of the trip experience.
A need existed to collect and analyze this type of
data, and to suggest possible management alternatives.
This study used a mailed questionnaire to a random
sample of past participants in order to collect basic
socio-economic data. The analysis was based on a 65%
response rate, and consisted of individual question tabulation
and multivariate data -cluster analysis.
The data show background characteristics of the
participants, reasons for taking the trip, reactions to
the experience, perceptions of problems associated with
the trips, reactions to crowded conditions, and needs for
regulatory policy concerning user intensities.

Chemical and Biological Problems in the Grand Canyon05 May 1973 (has links)
A survey of chemical and bacteriological water quality in the Grand Canyon was undertaken to assess possible health hazards to river travelers. The water quality of the main Colorado River channel is relatively stable with only slight increases in ionic concentration and bacteriological load with respect to distance from Lee Ferry and time over the summer season. The tributary streams show extreme temporal variability in chemical water quality and bacteriological contamination as a result of the summer rain and flood patterns in the tributary canyons. These side streams pose a definite health hazard to unwary river travelers. More extensive sampling is called for to determine the sources of this contamination and to protect the quality of the Grand Canyon experience.
