Alcogida Eco-Museum and exploring Puertito de los Molinos

We'd checked up on the Eco-Museum a couple of days earlier and all of us fancied a look around it so all 6 of us headed off therein time for 10 am opening. It was well worth a visit with tradition houses restored - from very basic ones to the main farmhouse in the village; added to that there were plenty of displays of crafts - embroidery, stone carving, weaving, basket making, bread making (we sampled that and it was very good!).
A few geological highlights:
Building stone: light coloured Pliocene sedimentary rock (the odd bit of lava seems to have crept in) with quoins of red cemented scoria from nearby Mta Bermeja.


Lumps of scoria are hammered into the bottom of wooden boards to make a threshing sledge.
The stone mason carving a mortar: he had a three sided shelter so that he could always keep out of the sun... neat!
Pestles and Mortars carved out of volcanic rock

 After calling in at the Visitor Centre to buy some fresh baked bread we went on down to Puertito de los Molinos where we'd heard there was a good fish restaurant at the back of the beach and we weren't disappointed. We were then thrilled to see some lovely exposures of volcanic lavas cut by at least 2, possibly 3, sets of dykes.
The headland north of Puertito de los Molinos. Volcanics cut by dykes at the base are eroded off forming a level platform on which have been deposited coastal/marine sediments (light coloured) and younger lava flows

A dyke with a badly eroded centre; the dark, chilled margins have fared rather better.

A mini-dyke - but it had such a clear chilled margin I had to include it!
