Duncan Dam Reservoir Archaeological Overview Assessment Final Report The pre-dam ortho images (with contour and TRIM overlay) were uploaded into a Trimble GeoXT GPS / with TerraSync datalogger to orient crews in pre-reservoir environments in real time. The proposed 50 m width linear transects (including outer extents and centre line) were uploaded into three separate Garmin Map60 GPS units to guide pedestrian traverses. Prior to field reconnaissance, logistical constraints required eliminating three (of the proposed thirteen) transects (4, 7 and 8) which were considered to be redundant in terms of representation.

5.0 RESULTS Duncan Dam Reservoir Archaeological Overview Assessment Final Report Field reconnaissance was carried out from May 7 and 10, 2010 by a six member Eagle Vision Geomatics & Archaeology Ltd. survey crew: Wayne Choquette, Melissa Knight, Robert Williams, John Nicholas, Mike Shottanana and James Wageman. All crew members participated in survey of each transect location. Problematic access necessitated elimination of two additional transects (1 & 12) from the field reconnaissance (i.e. Transect 1 was flooded while Transect 12 is on the right bank of the Duncan River, several hours of hiking from the nearest forest road). Therefore, priority was given to the remaining eight transects encompassing the largest expanse of contiguous target terrain relative to the time required to access them (2, 3, 5, 6, 9, 10, 11 and 13). Survey transects were examined via pedestrian traverses allowing for close visual inspection of drawdown area surfaces, focusing especially on exposures of remnant fine sediment and areas where such might be present associated with gravel reservoir lags atop identified pre-reservoir landforms. Survey proceeded via 10 - 20 m wide zigzag pedestrian transects within the survey transects which had been selected to sample specified landform and sediment exposures. Traverses of transects were tracked within the Garmin units while the Trimble recorded landform specific data, archaeological site data and geo-reference of digital photographs. It was necessary to adjust the proposed transects in the field as several locations (i.e. 3, 5, 6, 11 and 13) as defined on the pre-reservoir air photos were either outside the limits of the reservoir as it now exists, or the terrain to be captured by the models was more restricted than appeared on the air photos due to forest canopy closure at the time the photos were taken. Transect 9 and Transect 6 were not systematically surveyed as the target landforms (mapped relict beaches) were not observed within the reservoir draw down zone. The terrain associated with Transect 6 was found to be uniformly steep and heavily eroded (Plate TR6-1) and although a narrow terrace was observed a few metres above the reservoir full pool adjacent to the proposed transect location (most likely one of the mapped beaches), it is not presently affected by reservoir operations.
