The Flybye Springs, Northwest Territories, consist of 10 active vents and numerous small seeps that discharge sulphide- and barium-rich spring waters at an average temperature 8.5 °C. Oxidation of sulphide to sulphate drives precipitation of stellate and platy barite microcrystals in the proximal flow paths. Downstream, and in vent- and tributary-fed ponds, barite is precipitated among streamer and mat forming colonies of sulphur-tolerant microbes, including Thiothrix, Beggiatoa, Thioploca, Chromatium, Oscillatoria, fungi (dominantly Penicillium), and unicellular sulphate reducing bacteria. These microbes mediate barite saturation by adjusting redox gradients and via passive adsorption of barium ions to cell surfaces and extracellular polymeric substances. Passive biomineralization produces barite laminae in floating microbial mats, nanometric coatings, and micrometric encrustations around microbial cells and filaments, and local permineralization of Thiothrix, Beggiatoa, and Oscillatoria outer cell walls. Intracellular barium enrichment and (or) metabolic sulphur oxidation may be important to "active biomineralization" that produces nanometric barite globules on the tips of fungal hyphae, barite-filled cell cavities in Beggiatoa and Thiothrix, and baritized sulphur globules. Degradation of biomineralized cells generates detrital "microfossils," including barite tunnels, layered cylinders, solid cylindrical grains and chains of barite beads. The diversity of inorganic and biomineralized barite in the Flybye Springs flow path highlights the influence of ambient chemistry, microbial metabolism, and cellular structure on barite solubility and on the taphonomy of microfossils preserved in barite.

Sulphur Spring

Health resorts have been important landscape identity elements and economy drivers in European cities since the beginning of their development. The sea coastal area in Latvia is rich in sulphur springs that have been used for health procedures since 19th century. Kemeri resort in Jurmala City is known as a unique place that got its name from the forester house Kemeres where the first health procedures were performed by using sulphur spring mud. In 1836 Kemeri was declared as a resort and became known in the whole Russian Empire and later also in the Soviet Union. Significant landscape changes occurred after Latvia regained its independence in 1990, when the ownership of the land changed from the state to the private. Affected by disagreements between the new owners, lack of private and state investments, decrease of visitors from former Soviet Republics, insufficient capacity for competing with European resorts, the resorts in Latvia often became abandoned and forgotten. Historically valuable buildings and parks of the resorts were degraded, the number of inhabitants and visitors decreased. Today the regional government has found opportunities for re-development of Kemeri resort by searching for a new identity and re-branding the place. Re-branding has been used to enhance attractiveness of the place and increase economic benefits. Therefore, the aim of the study is to identify historic heritage values suitable for re-branding of the place and to analyse a potential development of the resort Kemeri. Assessment part of the article is based on historic heritage study by comparing historic and modern photography, field surveys to identify historic heritage values of the place and their influence on possible development scenarios. Historic heritage values were identified according to the Historicity and authenticity; Aesthetic quality and integrity; Social meaning. The other parts of the article are addressed to re-branding of the place that includes involvement of identified historic heritage values into the new identity to enhance functionality, recognisability and attractiveness of the resort Kemeri.

Materials belonging to the Sulphur Spring stage of the Cochise culture previously were identified on the prominent 1,274 m shoreline of Pleistocene Lake Cochise in southeastern Arizona. Dated ca. 12,000 to 11,000 years ago, the remains were suggested to represent an early Archaic manifestation deposited in ancient beach gravels, possibly contemporary with Clovis levels at the Lehner and Naco sites. New data based on stratigraphic analysis, correlated radiocarbon dates, together with artifactual remains indicate that the association of Sulphur Spring stage artifacts with the shoreline of Lake Cochise is problematical.

Big Game Hunting

AbstractIn 1955-56 the Arizona State Museum excavated an elephant-kill site on the Lehner ranch in the San Pedro valley, near Hereford, Arizona, and found 13 projectiles, mainly Clovis fluted points, eight butchering tools, and charcoal from two fires among the remains of nine immature mammoths and elements of horse, bison, and tapir. Bones and artifacts occurred on and in gravels of a former perennial stream exposed in the modern arroyo bank. Most or all of the animals were probably killed over a comparatively short period by hunters identified with the Llano complex by the Clovis points. The Lehner site and the nearby Naco site represent the southwesternmost extent of the presently known range of the Llano complex. The post-kill sequence of alluviation and erosion supports a geological age of 13,000 or more years for both bones and artifacts. Arizona, Michigan, and Copenhagen radiocarbon measurements of hearth charcoal indicate a date of 11,000 to 12,000 B.P. Since these dates are substantially older than the oldest radiocarbon assays for the Sulphur Spring stage of the Cochise culture, it is probable that the transition from big-game hunting to collecting is reflected in the change from Llano complex to Cochise culture, and that this shift in economic emphasis took place before the complete extinction of the late Pleistocene megafauna.

Radiocarbon dates from archaeological sites in Whitewater Draw, Arizona, place the Sulphur Spring stage of the Cochise Culture between 8000 and 10,000 yr B.P., and possibly back to 10,400 yr B.P. Geoarchaeological investigations of Whitewater Draw do not substantiate an earlier claim that Sulphur Spring stage ground stone artifacts are associated with extinct megafauna, nor the hypothesis that Sulphur Spring stage artifacts are specialized plant processing tools of the Clovis Culture.
