Origin And Developmental History Of Minnesota Lakes, H. E. Wright Jr.
Origin And Developmental History Of Minnesota Lakes, H. E. Wright Jr.
Journal of the Minnesota Academy of Science
ABSTRACT-Most lakes in Minnesota owe their origin directly or indirectly to glacial deposition or erosion 10,000 to 20,000 years ago. The lakes' shapes have since been modified by waves and currents near the shores and by the deposition of sediment off-shore-principally the sediment produced by growth of algae and other organisms. This sediment is a receptacle for pollen grains blown into the lake from the surrounding vegetation, and the stratigraphic succession of pollen grains records the postglacial vegetational and thus climatic history of the area. The sediment also preserves the fossils of microorganisms that reveal by their chemical composition the …
A Search For Ddt Residues In The Juneau Icefield, Alaska, Jon Edwin Barber, Russell S. Adams Jr.
A Search For Ddt Residues In The Juneau Icefield, Alaska, Jon Edwin Barber, Russell S. Adams Jr.
Journal of the Minnesota Academy of Science
The objectives of this study were: 1) to determine if DDT residues occurred in the ice of the Juneau Icefield, and 2) to devise a simple, inexpensive method of sampling glacial ice for pesticide residues. No DDT was found in the samples of ice collected strata spanning the 1963 to 1970 period. However, phthalate plasticizers were found in all samples and were assumed to be· due to contamination during collection. The elution time of the phthalate by gas chromatography was identical to that of p, p-DDT. Conversion of DDT to DDD by ultraviolet light was found to remove the phthalate. …

Glacial Lake Evidence In Western Minnesota As Interpreted From The Soil Survey, Raymond T. Diedrick, Richard H. Rust
Glacial Lake Evidence In Western Minnesota As Interpreted From The Soil Survey, Raymond T. Diedrick, Richard H. Rust
Journal of the Minnesota Academy of Science
Soil surveys in several counties in western Minnesota have revealed a soils pattern which provides geomorphic evidence for a previously unrecognized glacial lake. This glacial lake, here called Glacial Lake Benson, is about 60 miles long, 40 miles wide and of almost one million acres in area. Soils along its northern boundary are generally developed in coarse outwash. The central and southern portions of the lake basin have well-sorted silty soils, similar to those in Glacial Lake Agassiz. The elevation of the outer edge of the Benson basin is about 1,050 feet. Topographic maps were used to prepare transects which …
