FINAL Phase IB Underwater Archaeological Resources Report for Onondaga Lake Superfund Site Anomaly 33: Canal Boat Anomaly 33 Summary Table Anomaly Identification Canal Boat; NY Site Number 06740.012300 Remedial Impact Capping NRHP Eligibility Eligible Recommendation Anomaly Dataset Side Scan (2005) 321, 326 Magnetometer (2005) 947, 59, 949, 951, 953, 60, 955, 959, Side Scan (2010) 6/3/10 Sector Scan (2010) 6/5/10 ROV (2010) 6/9/10 Diver Observations Yes Diver Videography Yes Maps/Charts No Aerial Imagery No Historic Accounts No Research Results A33 is an intact, buried nineteenth century canal boat. The site was identified in the Underwater Workplan based on a complex magnetic signature and several small sonar returns. The site was investigated in June 2010, with the side scan sonar, sector scan sonar and a remotely operated vehicle. The site was dive verified in October 2010. The initial side scan and sector scan sonar data from A33 did not yield any targets which seemed likely to be a submerged cultural resource. The remotely operated vehicle survey located several upright timbers protruding from the bottom, however, the extremely silty bottom conditions and associated poor underwater visibility lead to inconclusive results. The timbers that could be seen had enough potential that A33 was recommended for dive verification, which was undertaken on October 27 and 28, 2010. This fieldwork lead to the discovery that A33 was an intact, almost entirely buried wooden canal boat. The upright timbers initially seen during the ROV work were determined to be the boat’s bitt posts and stem (Figure 113). The exposed portions of the stem, bitt posts and gunwale, although very limited, contained features diagnostic of a wooden nineteenth century canal boat. The vessel had a distinctively canal boat shaped bow with iron bands along the forward face of the stem, a rub strake in the bow and an iron traveler on the after face of the stem. The gunwale had fair leads, used to guide the boat’s towline, cut into it. The bitt posts were found immediately aft of the stem, with a buried windlass attached just below the sediment. The run of the boat’s hull contained no structural elements exposed above the lake bottom, however, structure was encountered with a probe 2 to 3 feet (.61 to .3m) below the sediment in numerous locations. Dive verification did eventually yield the very end of a wooden tiller bar and buried rudderpost located 95 feet 5 inches (29.1m) aft of the stem. The tiller had a tiller bar extender, another diagnostic canal boat feature, which is an iron band and loop around the tiller used to insert a long steering pole so that the boat could be steered from on top of the cabin. 169
FINAL Phase IB Underwater Archaeological Resources Report for Onondaga Lake Superfund Site The length of the vessel from stem to rudder post (95 feet 5 inches [29.1m]) is consistent with canal boats built between 1862 and 1915. The archaeological data collected from A33, although limited due to the sediment deposition, conclusively illustrates that the site is a buried canal boat. The remains that are visible (stem, tiller) represent the highest points on the vessel, with the exception of the cabin trunk and roof. The preservation of these elements indicates that the buried portion of the site is intact. A canal boat the size of A33 was 8 to 10 feet (2.4 to 3.1m) tall, suggesting the bottom of the vessel rests below 10 to 12 feet (3.1 to 3.7m) of sediment (Figure 114). Figure 113.
