Letter from W. W. Bass to Carl Hayden requesting the boundaries of the park be reconsidered as a large portion of the land is suitable for mining and farming.
Letter from Carl Hayden to W. W. Bass concerning the passing of the national park bill. Hayden states that he will try to make the bill as advantageous to Arizona miners and farmers as possible, but the land will either remain as a national monument or become a national park. A postscript is added concerning the land allocated for the Havasupai Tribe.
Mission: To regulate and support Arizona Agriculture in a manner that encourages farming, ranching and agribusiness, while protecting consumers and natural resources.
Amendments to the bill establishing the Grand Canyon a National Monument. Circa 1908.
In 2006, Arizona enacted legislation that directed the Arizona Geological Survey (AZGS) to map earth fissures in the state, required that the presence of earth fissures be disclosed in real estate transactions, and that the resultant earth fissure maps be made publicly available. In order to meet these statutory requirements, AZGS developed, for the first time, standards, procedures, and criteria for identifying, mapping, and characterizing earth fissures.
AZGS geologists identified earth fissures through a review of publications and reports, air photo analysis, and field reconnaissance. Using GPS, we collected relatively high-precision locations and descriptive data along the length of earth fissure surface exposures, and categorized them as either continuous or discontinuous. If we were not able to find and map previously reported fissures, we used the “reported, unconfirmed” category.
To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers were prepared. In Pima County, ranching is uniquely able to preserve the integrity of vast tracts of connected and unfragmented open space and wildlife habitat. This study reviews the effect of five alternative permit strategies on the County's ability to preserve unfragmented landscapes through conserving ranch lands.
This white paper has been created by Arizona Land Subsidence Group to help educate stakeholders and decision makers by describing the geological features and processes of land subsidence and earth fissures, and the hazards they create. This paper presents the current and future technical needs that exist in terms of basic knowledge, available data, and the state of professional practice.
