Unwrapping a bundle of Basketmaker II textiles from Old Man Cave disclosed two examples of a previously undocumented textile form: bifurcated tumplines. At more than twice the width of standard tumplines, these warp-faced plain weave bands of human hair cordage have one flat end, with the other splitting into two separate parallel bands—one longer and the other shorter. Both narrow bands terminate in tumpline suspension loops. Strains, breaks, and repairs indicate that these textiles served to carry loads. Rather than suspending the weight from the head and resting it on the back, this tumpline suspended weight in front with the textile draped over the shoulder. Knowledge of this new tumpband form allowed identification of an additional example in a museum. Radiocarbon dating confirms the Basketmaker II temporal affiliation. Final use of the Old Man Cave bifurcated tumplines was as a pair and likely related to transporting bodies for burial.

打开来自 Old Man Cave 的一捆 Basketmaker II 纺织品，发现了两个以前未记录的纺织品形式的例子：分叉的 tumplines。这些人发绳的经向平纹编织带的宽度是标准 tumplines 的两倍多，一端平坦，另一端分裂成两个独立的平行带——一个较长，另一个较短。两个窄带都终止于 tumpline 悬吊环。应变、断裂和修理表明这些纺织品用于承载负载。不是将重物悬挂在头部并将其放在背部，而是将重物悬挂在前面，织物披在肩上。了解这种新的腰带形式可以在博物馆中识别出一个额外的例子。放射性碳测年证实了 Basketmaker II 的时间隶属关系。
