Crushed and fragmented shell was observed, some of the shell being thermally altered (Plate 10). A few small fish bones were also observed. Profile GH 4 showed evidence of a 4 cm thick lens of shell midden at 38 cm BS and was comprised of crushed and broken clam and thermally altered mussel shell in a black brown loam matrix. It is assumed that much of the cultural deposit at this location has succumbed to natural erosion and storm surges. Plate 10. Profile Point KK3, showing lens of shell midden at 80 cm BS.

Fourteen shovel tests and two auger tests yielded positive results, and indicated that midden deposits ranged from 27 cm to 120 cm BS with an average thickness of 66.8 cm. In general, the upper level of the midden deposit was disturbed and characterized by dark brown rich organic silt-loam with fine grained sand and a significant amount of historic material and garbage encountered to an average depth of 35 cm below surface. In some places this upper disturbed deposit sat upon intact cultural deposit comprised of dark brown loam, and in others it sat directly on top of a greasy black-brown loam with crushed, fragmented, and whole shell (Plate 11), with an abundance of fish bone and urchin remains. The cultural deposits consistently rested upon non-cultural coarse yellowish beach sand. Plate 11. Shovel Test Location 2, Shovel Test G7, at the northwest end of DcSb-1 Dossier 13.0139 environmental services ltd. 882 Ministry of Environment – Mr. Kirby Villeneuve Page 53 Archaeological Impact Assessment of Sombrio Beach February 19, 2014 A series of shovel tests were excavated from the beach in front of the midden berm, extending northeast to the marsh behind the berm in order to develop a profile of the midden deposit (from southwest to northeast: K3, K2, K1, G1, G4, G5, G2, G3, and auger tests G1 and G2, pictured in Plate 12 and illustrated in Figure 7). The berm profile illustrates how the midden deposit would have built up behind the village houses lining the beach. The berm reaches a maximum height of 1.61 m above the berm base and drops to 0.87 m above the berm base for the height of the wetland behind the berm. This indicates that the wetland is anthropogenic in origin as water draining downslope behind DcSb-1 would have pooled behind the berm and thus creating the wetland. Plate 12. Looking northeast at line of shovel tests excavated to profile midden berm.

Shovel tests K17 and K25, and EU 1 are closest positive tests to the trail, lying on the trail’s southeast side and representing the northwest site boundary of DcSb-1. Shovel tests on the west side of the trail (specifically K16, K18, K23, and K27) were all negative, and testing at the proposed kiosk, signs, food cache and pit toilet (specifically K4, K5, and K6) also produced negative results, as well as a number of tests between. These negative non-cultural test were largely comprised of brown sand and clay (Plate 13) Plate 13. Shovel Test Location 2, Shovel Test PM1, example of negative tests. Particular attention was given to the wet area behind the midden berm, as there was a possibility of encountering water saturated cultural deposits. Four shovel tests (G2, G3, G4, and G5) and four auger tests (G1, G2, A2, and A3) were placed in the wet area. Of those tests, only two shovel tests (G4 and G2) and one auger test (A2) yielded positive results. All of the cultural components were above the water table and comprised of greasy organic loam with shell and faunal present. Negative tests typically contained organic rich silty clays, overlying a sandy basal deposit.

Sand and rounded cobbles were visible on the surface in many areas of this location, and poor soil development was confirmed by the two soil tests and an examination of the beachward scarp. They both showed evidence of duff atop coarse sand deposits with river-worn cobbles and pebbles (Plate 15). No cultural material was encountered at this location. Plate 14.

Looking at the deposits in the area of Shovel Test Location 4. 6.3 Evaluative Unit Results Two evaluative units (EUs) were excavated within the site boundaries of DcSb-1 in order to determine depth, integrity, and nature of the cultural deposits. The initial AIA plans only allowed for one EU, but given the high cultural and scientific value of the site, the excavation of another EU was generously permitted by MoE. For a detailed description of stratigraphy, please refer to Appendix B. 6.3.1 Evaluative Unit 1 EU 1 was located immediately southwest of the proposed campsite access trail (Plate 17). The EU was excavated to a depth of 47 cm below surface in arbitrary 10 cm layers after the first 17 cm of disturbed material was removed. The upper 17 cm deposit was a black-brown loam with 20% coarse sand, 15% rounded FCR, 15 to 20% sub-rounded to sub-angular pebbles and gravel, rootlets, with trace shell and frequent historic and modern material. Level 2 (17 to 27 cm BS) was characterized by greasy black-brown loam with 20% coarse sand, 35 to 40% crushed, fragmented and whole shell (predominantly California mussel, chiton, limpet, and a few clam), high amounts of fish bone, and large amounts of green and purple urchin spines and body fragments.

CALIFORNIA MARINE FISH LANDINGS FOR 1972 LEO PINKAS Marine Resources Region 1.1. INTRODUCTION The protection, propagation, and wise utilization of California's living marine resources (established as common property by statute, Section 1600, Fish and Game Code) is dependent upon the welding of biological, environment- al, economic, and sociological factors. Fundamental to each of these factors, as well as the entire management pro- cess, are harvest records. The California Department of Fish and Game began gathering commercial fisheries land- ing data in 1916. Commercial fish catches were first published in 1929 for the years 1926 and 1927. This report, the 32nd in the landing series, is for the calendar year 1972. It summarizes commercial fishing activities in marine as well as fresh waters and includes the catches of the sportfishing partyboat fleet. Preliminary landing data are published annually in the circular series which also enumerates certain fishery products produced from the catch.

  • Book Club Kit
    BOOK CLUB KIT LINDSAYHATTON.COM LINDSAY_HATTON /HATTTONLINDSAY Hello readers, I’m so happy you’ve chosen Monterey Bay for your book club. Monterey, California is a special place for many people. Its coastline is among the most famous in the world. Its aquarium welcomes nearly two million visitors every year. It has served as a muse for countless writers, artists, philosophers, and scientists, some of whom are characters in my book. I called Monterey home for the first twenty-one years of my life. During high school and college, I worked summers at the Monterey Bay Aquarium. I became well versed in the region’s colorful history and in the natural history of the bay. But to me, there was always something about my hometown that history alone couldn’t quite explain. There seemed to be an imagined tale of heartbreak and ambition just below the factual surface: an alternate founding legend that captured how it felt to stand knee-deep in a tank full of hungry bat rays, to watch the morning fog roll in, to be alone on Cannery Row at midnight and hear the whispers of ghosts. I like to think of Margot Fiske, the protagonist in Monterey Bay, as one of these ghosts. Unlike John Steinbeck and Ed Ricketts, she never actually existed. She is an invented composite of girls and women I’ve read about and known, and of girls and women I could have been. Through her, there are many questions I hope to explore. What is the price of inappropriate desire and its expression? Is it possible to both escape and embrace a family legacy? Do people belong to places, or do places belong to people? Is a true story the same as a story that tells the truth? When, if ever, is captivity preferable to freedom? For those of you who have spent time in Monterey, I hope the book recalls your best memories of this enigmatic and beloved town.

  • Layout Molluscs Program Guide
    Branches on the Tree of Life Molluscs Written and Photographed by David Denning and Bruce J. Russell Produced by BioMEDIA ASSOCIATES, ©2006 Running Time 18 minutes The Phylum Mollusca is the second most diverse phylum of living animals, with more than 60,000 known species alive today. Molluscs have also left a remarkable fossil record with over 40,000 described extinct species, some going back over 500 million years to early Cambrian times. This excellent fossil record is largely a result of the hard, calcifi ed shells produced by these extinct mollusc species. One of the earliest Molluscs groups was the Monoplacophora, which had limpet-like shells, but a distinctive body with pairs of gills in along the sides of the mantle cavity. This group is represented by a fossil of Scenella shown in this program which was found in the Burgess Shales of British Columbia. Only a few species of Monoplacophorans, such as the ‘living fossil’ Neopolina, survive today in very deep ocean basins. The word ‘mollusc’ means ‘soft-bodied’. The mollusc body is bilaterally symmetrical. Most Molluscs have a muscular foot, which can take a variety of forms, and is used variously for crawling, digging, or swimming. Most molluscs are protected by a hard shell made from calcium carbonate minerals extracted from the water. The shell is secreted along a rim of soft tissue called the mantle, which forms the mantle cavity hiding a delicate set of gills. While the gills are typically ‘feather-like’ in most species, some molluscs have modifi ed gills and others exchange oxygen and carbon dioxide directly through the skin.
