About the link to Mogollon rock piles

I was browsing through this link I provided earlier [Click here] and realized that this might be relevant to New England although it is about the southwest. What have we here? Cairns and alignments in the southwest desert. The author climbs the hills to survey them. He writes:

At the La Cruz site, on a hill along the Arroyo Tapacitas, the survey crew mapped a unique hilltop feature. This consisted of four lines of rock radiating out from a stone circle in a cross shape. (See Cross) The four arms were constructed of stacked fused-ash cobbles, ranging from four to five meters in length, and 30 to 40 centimeters in height. The arms were approximately aligned 45° off of the cardinal compass directions. A potentially related feature was found 150 meters southwest of the cross-like feature- it is a small cairn with a needle-like rock slab pointing up 60 cm from the center of the rock pile.See Alignment Stone)
