Fluted Points

AbstractIn an attempt to compare a large number of fluted points in the Eastern United States, metric data were coded on punch cards and analyzed statistically. A sample of fluted points from Virginia was tested in a trial study. It was found that some attributes showed significant but predictable clustering. The variation in fluting pattern between geographical areas within the state was significant.

Abstract The National Geodetic Survey (NGS) in cooperation with a number of federal agencies, state and local groups and universities is establishing GPS networks in the United States, east of the Rocky Mountains, which can be used to monitor strain and vertical deformation. These GPS networks are tied to a framework of some 14 fixed and mobile VLBI sites. In cooperation with the Nuclear Regulatory Commission (NRC), NGS established a 45 station GPS regional network in Nov.–Dec. 1987 which is tied to the VLBI framework. This network is scheduled for reobservation in 1989 and funds permitting, at regular intervals thereafter. A number of additional, more dense networks have been or are in the process of being established. The Tennessee Department of Transportation has established a 60 station statewide network to act as a reference network for surveying in conjunction with road construction. This network is expected to have an accuracy of a few parts in 107. NGS in cooperation with the NRC and the University of Maine established in 1986 a high accuracy GPS network in southeast Maine. In 1987 NGS in support of the Federal Aviation Administration (FAA) has established approximately 100 stations throughout Ohio with an accuracy in the 1:106 to 1:107 range. Toward the end of 1988, NGS, working in conjunction with several state agencies and the University of Florida, will establish a statewide network of about 140 stations with an accuracy in the 1:106 to 1:107 range. NGS, in cooperation with the Department of Energy, has also established a high accuracy to 1:107 to 1:108 GPS traverse from Florida to Maine connecting stations at tide gauge sites. The State of Texas is establishing a number of permanent GPS stations in support of highway surveying. These stations will allow strain monitoring across Texas at the 1:108 level. Additional networks are in the planning stage. It is clear that large numbers of high accuracy GPS networks are being established throughout the eastern United States. Many of these networks are being established for other than geophysical purposes. In many cases the state highway departments and others are interested only in 1:106 accuracy. As a practical matter this means that to assure 1:106 accuracy a few parts in 107 accuracy (1 to 3 cm over 100 kms) is often attained, but this is by no means certain. Also there are normally no plans for systematic resurveys, only replacement of destroyed monuments. A challenge to the geophysical community is to interact with the groups undertaking the high accuracy surveys to assure that, at points of geophysical interest, satisfactory accuracies are achieved during initial epoch measurements. This means that a satisfactory number of observations are obtained and high accuracy reduction methods are used in obtaining differential positions from the data. The geophysical community must also develop plans for resurvey of geophysically interesting network components on a systematic basis.

18Th Annual Meeting

For several years, I have had the pleasure of attending the annual meetings of the New Jersey Mosquito Extermination Association. These meetings are held at Atlantic City, usually about the middle of February. This year the 18th annual meeting was held on February 18, 19 and 20. One would think from the name of the organization that problems discussed at these annual meetings are concerned with mosquito control within the state of New Jersey.

Fluted Points

Since the scientific recognition of a paleo-Indian occupation of the Southwest and high Plains, beginning with the Folsom discoveries in 1927 (Roberts, 1940), the presence of man in the eastern United States prior to the earliest demonstrated cultures of the Archaic period has been suspected on the evidence of random surface finds of fluted points. Some of these artifacts have typologically been equated with the Clovis Fluted form (Krieger, 1947, pp. 10-13), while the greater number, showing considerable stylistic variability, have provisionally been designated “Ohio Fluted points” (Shetrone, 1936, pp. 240-256; Wormington, 1949, pp. 33-35).

The halictid bees of the genera Dufourea Lepeletier de Saint Fargeau (Rophitinae) and Dieunomia Cockerell (Nomiinae) occurring in Michigan are reviewed. Two new records for Michigan are provided: Dufourea harveyi (Cockerell), new status, and Dieunomia heteropoda (Say). This is also the first published record of D. harveyi in the eastern United States. The occurrence of Dieunomia in southwest Michigan is the first record of the subfamily Nomiinae for the state. Information on the biology and distribution of each species is summarized. An identification key to the Dufourea of the eastern United States is provided.

Fluted Points

AbstractAn obsidian fluted point was found on the slope of a gorge near San Rafael, just west of Guatemala City. The point probably washed from hills on the thick beds of volcanics through which the gorge is cut. This would confirm previous beliefs that the paleo-Indian occupation of the area post-dates the volcanics. The San Rafael point resembles the fluted points from Costa Rica and Durango, Mexico, and Clovis forms from the eastern United States. Thus, paleo-Indian influences from the north into Middle America may have been of predominately eastern rather than western origins.

The state of Mississippi is one of the least botanically explored areas in the eastern United States. A floristic survey of Choctaw County, Mississippi, was conducted from November 2009 through November 2017 in order to document the vascular flora and describe its plant communities. The county is located in the central portion of the state within the North Central Plateau physiographic region, an area dominated by dissected uplands with acidic to circumneutral sandy-clay soils. Three major river basins occur in the county, including the Big Black River, Noxubee River, and Pearl River. A total of 950 vascular plant species (958 taxa including varieties, subspecies, and recognized hybrids) was recorded. Three-hundred thirteen of these taxa were new county records. Twenty-eight species of special concern as designated by the Mississippi Natural Heritage Program were documented. Approximately 15 percent of the flora is considered non-native to the United States. Eight primary plant communities are also described.
