Cache number 1970 was found in primary mound number 2 in the northwest section of mound 72. With a total of 451 arrow points in this cache it's the largest cache of points that was found. Only four different point types were identified in this cache. The point type with the highest number has 258 (type I) triple-notched serrated and un-serrated Cahokia points made of white Burlington chert. The second largest number is 178 (type VII) serrated Madison points most of which are made of Kaolin chert. The third largest number is represented by 13 (type VIII) triple-notched serrated Cahokia points and the fourth type has 2 (type IX) double-notched serrated Cahokia points. These points were apparently once held in a container made of some type of organic material that did not survive. A few bone harpoon points can be seen scattered around the edges of the cache.
