Persistently unstable hillslopes in Northern California are ideally suited to the study of the dynamics and morphological signature of earthflows, as the deeply sheared melange lithology, high seasonal rainfall, and fast uplift rates promote widespread deep-seated landsliding. In addition to identifying multiple active landslides in the region, L-band InSAR reveals varying deformation rates in the accumulation, transport, and toe regions of the Boulder Creek earthflow. Downslope displacement rates up to 1.8 m/yr are observed on the earthflow over a I-year period. The pattern of deformation is similar to that observed from 1944-2006 inferred from aerial photography. Interferograms highlight spatially variable rates controlled by lithology and gullies, and movement correlates with seasonal rainfall with a phase lag of ~2 months. / Committee in Charge: Dr. Joshua J.

The Strachan Creek area is on the east shore of Howe Sound about three miles north of the town of Horseshoe Bay, B.C. The rocks of the area consist of migmatite of the Bowen Island group, volcanic rocks of the Gambier group, plutonic rocks of the Coast Intrusions, and late basic and acidic dykes. These rocks are described and their relationships discussed, A striking feature of the Strachan Creek area is the banding in the diorite, one of the units of the Coast Intrusions. Each complete band is a couplet composed of one light- and one dark-coloured layer, one layer grading into the other. The light-coloured layer is composed mostly of plagioclase, whereas the dark-coloured layer is composed mostly of hornblende and magnetite. Generally, the ratio of hornblende (plus magnetite) to plagioclase decreases downward from a sharp contact, the couplets thus resembling inverted "graded-bedding". The author tentatively concludes that the banding in the diorite originated by a process of differentiation and crystal rising within a cooling diorite magma. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

The Wasootch Creek area is representative of the Rocky Mountain Front Range of southern Alberta. It is underlain by rocks of the Middle Cambrian, Upper Devonian, Mississippian, Permain and Lower Triassic, of which carbonates constitute the largest part. The Cambrian formations are correlated with the Eldon, Pika and Arctomys of the Bow Valley region. The Ghost River or Arctomys formation has on one fault block been removed by pre-Devonian erosion. The area is bounded on the west by the Cascade Coal Basin and on the east by the McConnell fault. Between these two structures are several high angle, westward dipping, reverse faults named from west to east Lac des Arcs, Exshaw, Porcupine, and West McConnell. Mature disection of the fault blocks has produced excellent correlation of rock hardness with topography. The McConnell fault consists of two thrusts which merge at Kananaskis Gap. South of Kananaskis Gap the two thrusts are designated McConnell and West McConnell. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

This is a study of administrative confusion and uncertainty which has beset development of an important part of Vancouver's industrial waterfront. False Creek is a two-mile long, twenty-foot deep inlet. Half the residential area of Vancouver is separated from the commercial center by this waterway and its shore is extensively occupied by industry. Originally the inlet was more than twice its present size, but the eastern half and a central mud-flat "bay" were reclaimed by the federal government prior to the First World War. Until 1924 the federal government claimed title to the bed and foreshore but in that year acknowledged the province's claim. It retained, however, the reclaimed area known as Granville Island and owns a large tract of Indian reserve land near the False Creek mouth. At the turn of the century the city was given title to the eastern half of the bed and foreshore, and later made the reclaimed portion available to the Great Northern and Canadian National Railways. The Canadian Pacific Railway owns almost all the upland lots on both the north and south shore of the waterway as it exists today. These are occupied either as terminal yards or under lease. Headlines have been established along its shore and the Navigable Waters Protection Act applies. False Creek has been a problem area because it is both an obstacle and an industrial area of high utility and potential. The city administration has been able to cope with the former, limited only by the funds available. Any over-all development, however, has been virtually impossible because of: 1) a confusion (before 1924) as to the spheres of responsibility of the senior governments, 2) their tendency generally to act without consideration for the over-all development, and 3) the total lack of co-operation between themselves or with the city in furthering comprehensive economic development. This has meant that the only development, apart from the federal reclamation, has been the result of private enterprise. It has been the good fortune of the city that this has never, yet, been contrary to the over-all potentialities of the area. Recent action by the federal government indicates that the Indian reserve property may be disposed of for purposes inimical to the best economic use of the shore. There appears to be no possibility of the city developing the waterway comprehensively by its own efforts, nor any likelihood that either or both senior governments will do so. The answer may lie in a statutory corporation publicly and privately owned, perhaps on the order of the English "mixed undertaking". Such or similar action would be facilitated if the city were able to acquire the False Creek land presently held by the federal government, perhaps by accepting it in payment for the city-owned (1954) airport. / Arts, Faculty of / Political Science, Department of / Graduate

This study investigates the geological setting of the Harper Creek copper deposit. The relation of the deposit to structure and stratigraphy as well as the age and nature of the mineralization are discussed. Copper mineralization is confined to tabular-shaped zones within metasedimentary and metavolcanic rocks of the Eagle Bay Formation. Although mineralization does not appear to be stratigraphically controlled, stratigraphy was important for the locallization of higher-grade material. Large-scale structures appear to have had an important role in the channeling of 'ore-forming' fluids. The deposit is thought to be genetically related to the formation of a large east-west oriented antiform. Mineralizing fluids of probable hydrothermal metamorphic origin migrated into this structure and replaced favorable host rocks. Although tenuous, evidence presented suggests the age of mineralization is between Upper Triassic (Karnian or Lower Norian) and Lower Jurassic-Upper Triassic. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

Globally we are experiencing a biodiversity crisis and potentially a sixth mass extinction event. Plant specimens are one of the best, most concrete records of biodiversity that we can create. Despite this, the rate of plant collecting has declined steeply since World War II. Now more than ever, plant collections are vital, both for the purpose of quantifying the plant biodiversity in an area and for discovering previously unrecognized diversity. In Chapter 1, we conducted a floristic survey of the Cal Poly Swanton Pacific Ranch. The Swanton Pacific Ranch (SPR) is located north of the small town of Davenport California, in Santa Cruz county. SPR is 3,200 acres and contains areas of salt marsh, coastal bluff, coastal prairie, riparian forest, redwood forest, mixed conifer forest and chaparral in approximate ascending order of elevation. The property extends over an elevational gradient from 0 m to 420 m (1400 ft). We documented 634 taxa at SPR. In total, 974 specimens were collected during this project, 405 specimens in 2017 and 569 in 2019. We reviewed 211 historic specimens. We vouchered 546 taxa between 2017 and 2019 and observed but did not collect 6 taxa. 53 taxa are represented from historic collections and were not relocated. There are 30 taxa listed as historically present from personal observations of the authors but without vouchers. Though these do not have the same value as a physical specimen, we believe that all information is valuable and have included them with a clear indication of the source of the record. There were 465 native and 169 non-native taxa documented in the study area. There were 93 families represented, with Asteraceae, Poaceae and Fabaceae be ing the top three most speciose respectively. There were 83 taxa noted as locally rare following Neubauer, of these 16 taxa have a California Native Plant Society (CNPS) rare plant rank. We vouchered one new taxon for Santa Cruz County, Senecio aphanactis, which has a CNPS rare plant rank of 2B.2 In Chapter 2, we describe a new combination in the Sanicula crassicaulis species complex. During the project detailed in Chapter 1, we observed and collected several specimens that keyed to Sanicula crassicaulis Poepp. ex. D.C. but were notably distinct from other S. crassicaulis that we collected in the area. On further investigation, we found that these plants match the type specimen of S. nudicaulis Hook & Arn., described in 1839 and later synonymized with S. crassicaulis. This taxon is distinguished primarily by its long, sinuate marginal leaf trichomes, in contrast to the short, straight marginal trichomes of S. crassicaulis. Additionally, the length of the most proximal prickles on the schizocarps is about the same as the length of the most distal rather than the distal prickles being much longer as in S. crassicaulis and the angle of attachment of the prickles is more or less perpendicular as opposed to acute in S. crassicaulis. The known range of this taxon is between the San Francisco Bay Area and Santa Barbara County, generally near the coast. Here we recognize this taxon as a variety in S. crassicaulis, Sanicula crassicaulis var. nudicaulis. We provide a diagnosis, a map of the known range of the taxon and a key to the varieties of S. crassicaulis. Overall this project has significantly increased or knowledge and documentation of the flora of both SPR and Santa Cruz county. In addition to the immediate benefits of this study (a complete species list for SPR, the discovery of a new taxon, and the mapping of all rare species at SPR) we have also contributed almost 1,000 physical specimens to the Cal Poly Hoover herbarium which may be used in future taxonomic and ecological studies.
