Rivers of Stone, Rivers Within Stone

(Rock Art in Ancient Puerto Rico)– Peter G. Roe
“Rock art has eluded quantification, pictographs and petrogylphs tend not to be regarded as fit subjects for “scientific” study. Because of that abdication, many amateurs have rushed in to fill the void, some competent and cautious, others rash and sloppy, reading all sorts of bizarre notions into the “ultimate Rorschach test” that is rock art (page 298).”

The Red Rock of Randolph MA

Driving south of Blue Hill you'll see reddish rock next to the highway, especially as you turn south on Rt 24 in Randolph. Always wanted to find rock piles made out of the red rock:

Note how the split is wedged and covered with other rocks.  Here is one more:
 These are next to Canton Street, by a spring:
From here the water drops down into Ponkapoag Pond:
Years ago, Bruce McAleer and I explored the north shore of this pond - a place of old hotels and resort paraphernalia. I guess the bit of woods on the south shore is less disturbed. Anyway, we hoped to find piles like the ones above, but never did.
The internet tells me this red rock is part of the Wamsutta Formation which apparently is also related to the reddish rhyolite we see an occasional arrowhead made from.

Burn to reveal unusual stone prehistoric features

BILLINGS (Montana) - "Using a controlled burn this spring, Havre archaeologist Josh Chase hopes to reveal a prehistoric site along the Milk River that contains large rock effigies resembling a turtle and a human figure.
“It’s not something you run into every day,” said Chase, who works for the Bureau of Land Management. “It’s been identified as being unique for a really long time.”
   The 800-acre site is protected as an area of critical environmental concern because of its historic value. Chase said within the larger area are the 300 acres where the majority of the artifacts are located — drive lines to herd bison off a cliff, teepee rings, rock cairns and the large figures that are “reminiscent of religiously significant” creations like medicine wheels.
   “They are some pretty significant rocks, too — several hundred pounds,” Chase said. “It was a concentrated effort to make the features.”"

Forgotten Monuments of Northern Sweden

From Past Horizons [click here]. Hmm...now, where have we seen this sort of thing before? Oh yeah, farmers in Northern Sweden had to clear their fields too.
