Dartmoor: Pew Tor and Heckwood Tor

Heckwood Tor

It was another one of those days where a minor walk would have to suffice. This time taking in Pew Tor and other outcrops in the vicinity, including a possible new outcrop.

Firstly, the short walk to Sampford Tor, or Little Pu Tor. A very disappointing pile of rocks, although I believe I didn't explore it enough so a revisit is in the diary, especially as Pew is nearby.

Next stop, Pew Tor. An absolutely exceptional sprawl of outcrops with beautiful granite geology (microgranite), great views for little effort and a very pleasing tor to be at. Certainly worth a visit for any new tor bagger.

I left the family to make for a small, separate outcrop south of Heckwood Tor. I dubbed it Little Heckwood Tor for its recognition. Even if it doesn't qualify ''tor status'', still pay a visit at SX 5362 7355.

Little Heckwood Tor appears to be quarried and partly ruined, so I wonder if the stonecutters took some of this granite as they couldn't take any from Pew? Who knows!

Heckwood Tor is much better than I first thought; its lowly appearance on the hill giving little indication to its size. Multiple outcrops on a gentle hill, like most of the tors here, emerging from the ground, it offers good views of King's Tor and Vixen Tor.

Now it was time to return to Pew Tor and visit the small quarry at Sampford Tor. I gave Feather Tor a miss.

We stopped off at Two Bridges for a light snack but I chose to seek out ''Two Bridges Quarry Tor'' - buried in the Wistman's Wood car park, it was obvious, probably how tors would've protruded from the ground before weathering.

David Leslie Linton, a geologist, is credited for his work by Devon.Gov.UK"It is one of the best used localities for demonstrating proposed mechanisms for granite decomposition including chemical weathering, pneumatolytic alteration as well as physical disintegration and weathering. The latest evidence from the site is probably the most convincing and suggests that the weathering of the Dartmoor granite was selective and that it probably occurred under a warm and mildly humid climate. Major difficulties still remain, however, in assessing the relative effects of hydrothermal alteration and chemical weathering where they occur together in one section, a situation believed by some to occur at Two Bridges Quarry."
