MAP EXPLANATIONRed lines represent the location of continuous earth fissures manifested as open cracks orgullies.Orange lines represent the location of discontinuous earth fissures manifested as elongatedto circular depressions or as abbreviated or irregular linear depressions. Thesediscontinuous surface features frequently represent an incipient surface expression of anearth fissure.Yellow lines represent the location of fissures confirmed by non-AZGS personnel or clearevidence of earth fissures on aerial imagery. Traditional field investigation of these featuresby AZGS was hindered by agricultural or urban modification of the land surface.Green lines represent the approximate locations of unconfirmed earth fissures, defined asfissures which could not be confirmed by surface investigations by AZGS geologists, butwhich have been previously reported by Professional Geologists in published documents ormaps.The outline of the Study Area is shown in blue. The limits of the study area are based oninterpretation of modern and recent ground subsidence data provided by the ArizonaDepartment of Water Resources. Historical and modern aerial photos taken within thisarea were searched for anomalous lineaments. These lineaments were then investigated inthe field to determine if there was any evidence of earth fissures.

Notice The State of Arizona has made a reasonable effort to ensure the accuracy of this map when it was produced, but errors may be present and the state of Arizona does not guarantee its accuracy. The map supplements, and is not a substitute for, a professional inspection of property for defects and conditions.
Introduction This is one of a series of earth fissure maps prepared by the Arizona Geological Survey (AZGS) in accordance with Ariz. Rev. Stat. § 27-152.01(3). AZGS collected location information from previously conducted earth fissure studies, reviewed available remote-sensing aerial and satellite imagery, and conducted surface site investigations throughout the study area. A reasonable effort was made to identify all earth fissures in the study area. Nonetheless, some fissures may remain unmapped as a result of one or more of the following:
1) Existing fissures may have been masked by construction or agricultural activities.
2) Incipient fissures may lack clear surface expression. 3) The surface expression of fissures changes
constantly as new earth fissures develop and old earth fissures fill in. A blank area on the map does not guarantee earth fissures are not present. However, blank areas within the study area boundary have been investigated, and no surface evidence of fissures was found as of the date of map publication. Determining the presence or absence of a fissure at any specific site may require additional mapping and/or geotechnical analysis.
