Duncan Dam Reservoir Archaeological Overview Assessment Final Report Plate TR6-1: Steep and eroded terrain in drawdown zone at the edge of the Duncan Reservoir. (MK100510_068) During the field reconnaissance, transect orientation was also adjusted laterally or longitudinally so that survey overlapped more completely with the drawdown zone (i.e. Transects 5 and 11), or so that only the portions within the reservoir study area were surveyed (i.e. Transects 3 and 13). Systematic survey was conducted of transect locations 2, 3, 5, 10, 11 and 13. A detailed description of results per transect including landforms surveyed, observed cultural materials, and preliminary archaeological potential summaries proceed the corresponding maps and photo documentation, all of which are provided in Sections 5.1 – 5.6. A summary of the field reconnaissance results follows in Section 5.7. Eagle Vision Geomatics & Archaeology Ltd. 40 November 28, 2010
5.1 Transect 2 Duncan Dam Reservoir Archaeological Overview Assessment Final Report Transect 2 encompassed a small valley on the "peninsula" south of Jubilee Point. This is a unique feature in the reservoir in that it is situated on this peninsula, which is itself a unique landscape feature in addition to being a very short drainage (< 2 km long) that contains a small spring-fed lake (Figure 5-1, Plate TR2-1). In addition to sampling such a unique setting, this transect was also proposed to include the beach at the mouth of the valley where archaeological site EcQf-2 was reported, which had not been revisited since it was originally recorded. All land and resource use models are tested by this transect. On May 7, 2010, the six person crew traversed the transect from north to south surveying a total area of 20.6 ha. The transect as surveyed in the field started further north than originally proposed to encompass the entire valley within the reservoir drawdown zone (Figure 5-1. 1). At the conclusion of the May 7 th field day, archaeological site EcQf-7 (EcQf-T10-05) was identified and recorded upon a return trip May 10, 2010 (Figure 5-2). 5.1.1 Landforms The valley extends northward beyond the reservoir; that part of it within was found to be a relatively flat-bottomed basin. At the north end of the transect is a gently sloping, lightly vegetated reservoir beach (Plate TR2-2) where remnants of burn piles and a few patches of Bf soil horizon were observed. The west side of the valley is steep and rocky, even precipitous west of the small lake. The east side, however, is more gently sloping and sandy, and appears to be quite heavily reworked by wind and especially reservoir waters as the valley faces into the prevailing winds. The bottom of the valley is mostly quite level, poorly drained and swampy, being watered by springs. North of the small lake, the valley bottom is characterized by numerous cedar stumps while much reservoir sediment has been deposited around the lake. Where the transect nears pre-dam Duncan Lake, the undulating gently sloping apron along the east side gives way to a complex series of level terraces and beach ridges. The largest is on the highest terrace and is vegetated (Plate TR2-3); its age is uncertain. The south end of the next lower terrace is capped by several fresh 1 - 2 m high reservoir beach ridges of coarse sand and gravel. The lowest terrace slopes southward and, by reservoir-related deflation and reworking, merges with the natural beach of pre-dam Duncan Lake formed by wave action against the resistant bedrock ridge on the northwest (Plates TR2-4,TR-5).
