The most prominent of these features are the spectacular rock spires that attracted visitors, beginning with commentary in the journals of travelers to California during the Gold Rush of 1849. We studied the geology of the Reserve to update past mapping of the bedrock, to depict and understand the surficial geology, and to study the processes of formation and decay of the rock spires. The geology is presented in Geographic Information System format that can be combined with other information on the Reserve. Bedrock of the Albion Mountains records a long and complex history spanning more than 2.5 billion years. Early intrusive activity was followed by sedimentation that lasted intermittently more than a billion years in both continental and marine settings. About 100-200 million years ago, mountain building caused metamorphism of the rocks, and later (100-7 million years ago) destruction of the mountains led to the structural assembly seen today. The final chapters in this bedrock history were intrusion of the Almo pluton 28 million years ago, volcanism about 10 million years ago, and continental extensional faulting flanking the Almo pluton. The National Reserve centers on three upland basins of gently undulating topography. The basins are ringed by high mountains and spines of rock pinnacles; each is drained to the east through a canyon cut into resistant bedrock, and ultimately drains to the Raft River. Resistant quartzite underlies most of the high mountains, whereas the lower lying upland basins are underlain by granite. It is this granite that erodes to form the picturesque pinnacles. Pinnacles are shaped by joints along which the rock is more readily weathered. The rock surfaces of the pinnacles display cavernous weathering and durable crusts. Joints, crusts, and weathering are the main features identifiable for inventories of the fragility of the rock formations. Most surficial materials surrounding and overlying the bedrock were deposited as alluvial fans and colluvium, although many other kinds of surficial materials are present that were deposited by a variety of surficial processes. The alluvium and colluvium appear to accumulate very slowly in all but the most active areas, such as the low parts of the upland basins. However, the slow accumulation of deposits does not imply stability of alluvial and colluvial surfaces because processes by which these deposits move, such as soil creep, landsliding, and debris flows, can be destructive to park infrastructure and life. Active stream channels and the steeper colluvial slopes are sites of repeated destructive events and are best avoided for construction of facilities. A newly discovered fault that passes through the town of Almo offsets Pleistocene alluvial materials as much as 5 meters (18 ft) but does not appear to offset Holocene materials. Infrequent modern micro-seismicity and a larger poorly located earthquake that occurred in the area several decades ago raise the possibility that local earthquakes could shake the Reserve severely in the future. Purpose: Support of DOI sister agencies Supplemental_Information: The primary layer is the geology layer (ciro_geo), which consists of both polygon features and arc features that describes map units (polygons), and depositional contacts, faults (which may or may not be polygon bounding features) and map boundaries. Geologic unit descriptions are given in the accompanying pamphlet Map units (polygons) are described in the polygon attribute table (ciro_geo.pat). The identities of the map units are recorded in the PTYPE field by map label (i.e. Qia). For a description of the map units, consult the PostScript or PDF explanation pamphlets in this report or the printable map sheet. Geologic lines (arcs) are recorded as strings of vectors and are described in the arc attribute table (ciro_geo.aat). They define the boundaries of the map units, the faults, and the map boundaries. These distinctions, including the geologic identities of the unit boundaries, are recorded in the LTYPE field. Attributes for geologic lines generally follow a scheme of the type of geologic line (i.e. fault), followed by a locational and/or scientific modifier (i.e. approx. located or queried).

Logical_Consistency_Report: Geologic lines attributed as a 'contact' do not separate geologic map units of the same type, and are not considered as 'dangles'. All geologic polygons are attributed with map unit designators found in the Description of Map Units Completeness_Report: This database is preliminary and may be updated in the future, if needed Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Accuracy of line locations is carried in the database (certain vs. approximate) and displayed by different line symbols (solid vs. dashed lines) in the cartographic display. For the purpose of this database, solid lines (certain attribute) represent contacts and faults located with an accuracy greater than 10 m and commonly greater than 5 m. Dashed lines (approximate attribute) represent less certainly located features: contacts and faults located with an accuracy of 10 to 15 m. Lineaments are lines whose positions do not affect location of polygons; they are located with an accuracy of 25 m.
