Description
These earth fissure data were prepared by the Arizona Geological Survey (“AZGS”) in accordance with Ariz. Rev. Stat. § 27-152.01(3). Shapefiles – This product includes two shapefiles for viewing using ESRI ArcGIS Desktop software. • EarthFissureTrace v.11.06.17zip file: This line shapefile displays the surface trace of earth fissures mapped by the AZGS, as well as reported, unconfirmed earth fissures within study area boundaries. Attribute Information: FissType: Classification of an earth fissure trace. • Continuous earth fissures manifested as open cracks or gullies. • Discontinuous earth fissures manifested as elongated to circular depressions or as abbreviated or irregular linear depressions. These discontinuous surface features frequently represent an incipient surface expression of an earth fissure. • Reported, unconfirmed earth fissures are defined as fissures which could not be confirmed by surface investigations by AZGS geologists, but which have been previously reported by Professional Geologists in published documents or maps. MappedDate: Date of most recent fissure observation. • MapExtent. This polygon shapefile displays the extent of study areas included in the current version of DI-39. A blank area on the map does not guarantee earth fissures are not present. However, blank areas within a study area boundary have been investigated, and no surface evidence of fissures was found as of the date of publication for that particular study area. Determining the presence or absence of a fissure at any specific site may require additional mapping and/or geotechnical analysis. Attribute Information: MappedDate: Date of most recent mapping in Study Area. Metadata – Text file containing FGDC standard metadata for the EarthFissureTrace062209 shapefile
