Abstract Horseshoe Lake and the Marion Lake scar, along the Red River, southern Manitoba, were cored to investigate the timing of the meander cutoffs and the sedimentology of the channel in-fill deposits. The Horseshoe Lake core, 10.75 m long, consists of 9.73 m of silt-rich deposits inferred to be lacustrine from 0 to 4 m deep, transitional from 4 to 5 m deep and alluvial below 5 m deep. Four wood and charcoal specimens sampled from the core yielded radiocarbon ages of 310 ± 40, 1730 ± 50, 2040 ± 50 and 2240 ± 50 BP. The Marion Lake core, 16.77 m long, consists of 14.73 m of silt-rich deposits inferred to be lacustrine from 0 to 5 m deep and alluvial below 8.5 m deep; the transition is indistinct and falls between 5 to 8.5 m deep. Four wood samples from the fluvial deposits yielded radiocarbon ages of 1600 ± 40, 1700 ± 40, 1660 ± 40 and 1620 ± 40 BP. The cutoffs that led to the formation of Horseshoe and Marion lakes are interpreted to have occurred at ~1990 and ~1520 cal BP or shortly thereafter, respectively. The silt-rich, alluvial-lacustrine deposits in the lakes lack structural and textural characteristics that can be readily recognized in core to distinguish the depositional environments. The absence of coarse sediments at the base of the fluvial units at both sites implies that minor to negligible amounts of sand were transported along the thalwegs of the channels prior to the meanders being cutoff. The dominance of silt within the oxbow deposits reflects sediment supply as the geomorphic setting of the river is within an extensive glaciolacustrine clay plain.

A pit feature containing Tchefuncte-like pottery, a Gary point, and fauna) remains recently was investigated at the Swan Lake Site (168011) located near Willow Chute Bayou in the Red River floodplain of eastern Bossier Parish. Three charcoal samples from the pit yielded radiocarbon ages of 2020 + /-60 B. P., 1830+/-70 B.P., and 1690+/-80 B.P. making this the earliest well-dated context in northwestern Louisiana containing ceramics. The most conspicuous feature at the site is a mound, now approximately 2.5 m high and about 25 min diameter. Clarence Webb first recorded the site, but only made a short description: "Solitary mound on n-east shore of Swan Lake, which is an old Red River channel. Is circular in shape, approx. 8-10 ft. high, 60 ft. at the base and 20 ft. on summit. Has several shallow trial holes on top, appears to be built up of sand -- no sherds found on or around mound -- trial holes show mostly sandy soil near clay out in field. In one or two places 3 to 4 inches dark soil found. In nearby field, 1 rough spear head found." Since Webb's initial visit the landowners have collected numerous artifacts from the site surface. Most of the decorated pottery consists of Early to Middle Caddoan Period types suggesting that the mound is related to those at the nearby Vanceville (16807) and Werner (16808) sites. However, also present are a large number of Gary points and several sherds similar to those recovered from the Bellevue Site (16BO4) indicating that an earlier occupation is represented as well.
