Area 12

This is the situated on the slopes above Culiembro. All the caves were spotted by Richard and Fred while en route to or during a climbing trip in the Central Massif. None have yet been entered; they are of interest because they may be fossil resurgences for 2/7.

$\O$
1/12
Visible from Oston, at an altitude of about 1150m. A round transected phreatic passage in a cliff. This will require a tricky climb to reach.
$\O$
2/12
To the left of 1/12 at an altitude of about 1050m. A huge hole (about 15m by 10m) lurking at the head of its own little gorge, with a small wood in it. Looks like a fossil resurgence for 2/7.
$\O$
3/12
Below the Oston - Carmameña path and marked on the map. A massive hole leading in the direction of Carmameña. This might have nothing to do with 2/7.
$\O$
4/12
About 150m above and slightly to the left of Cueva Culiembro, looking like a transected phreatic passage. Access would require being guided from the other side of the gorge, using radio or semaphore.
$\O$
5/12
Between the Valle Extremero and Valle de Trea, about 2/3 of the way towards the Trea path, and about half way up to Huerta del Rey. Looks like a scoop but difficult to assess.
$\otimes$
6/12
Location: On Culiembro path, obvious large entrance in cliff at altitude of around 800m.
Description: Might be 3/12. Chokes immediately.
$\otimes$
7/12
Location: A bit below 6/12, another large entrance.
Description: This might be 3/12 too. An artificial staircase of rock leads up to a wooden fence across the entrance. Chokes immediately.
$\otimes$
8/12
Location: Follow the higher of the two Culiembro paths from Oston. Where it starts zig-zagging down the valley go straight on at the first bend and follow a goat track round onto the rib. Climb down and continue traversing downwards to meet a narrow and exposed goat track round the edge of the rib to suddenly arrive at the cave.
Description: Chokes immediately.
$\otimes$
9/12
Location: Same height as Oston, on a bearing of 50${}^\circ$to Oston.
Description: Triangular entrance 3m high, 1.5m wide. Chokes immediately.
$\otimes$
10/12
Location: 40m above 9/12.
Description: Large entrance under overhang with fir tree in entrance. Large chamber with artificial walls at back. Crawl at back chokes immediately. Climb to right leads to second chamber with 10cm wide continuation.
