The bluestones in this phase of construction come from Whales, some 240 miles away. Each of these stone weigh upwards of five tons each and were moved while on land by log rollers, than floated across the dangerous Bristol Channel, than finally moved to their resting place by the log rollers again. "Nothing like this feat of transportation was ever attempted by any other peoples anywhere in prehistoric Britain- (Hawkins 64).
During the third phase of building after 1700 B.C., the incomplete circles were removed and replaced with 81 or more, huge sarsen boulders (figure 1) from the Marlborough Downs. This is the same material as the heel stone. These massive blocks average 20 tons and were moved south from a site twenty miles to the north. Since these people still did not have the wheel at this time, the stones were dragged over hills using sleds and log rollers. "The task of moving the sarsens . . . would have kept a thousand men busy for seven full years- (Hawkins 66). After they arrived at the Stonehenge site, the sarsens were shaped and polished. They were than placed in the same locations as the previous stones, but in a very different pattern. These stones were placed in the now familiar "trilithon- format, two upright stones capped with a lintel stone. The upright stones make use of entasis which shows sophisticated and advanced skills in stone cutting. The internal circle was fashioned into a horseshoe opening towards the heel stone and the Avenue. The outer circle encompassed the inner circle completely. The bluestones of phase two were than brought back and arranged in circles within the new sarsen circles. Oddly, they were almost immediately removed. Than the alter stone was placed within the sarsen horseshoe and a series of holes were dug and filled. These holes, known as the Y and Z holes line up with the previously created Aubrey holes. Finally, the builders re-erected the bluestone circles (Hawkins 40-60).
