Montanon Negro

 

 

On the way to the Pinos del Galdar road passed the Montanon Negro, a cinder cone of recent origin, at least for this island

It is possibly true that not better place exists to watch plant succession, and erosion possesses, than on this erstwhile pristine cone.

Pico de Galdar

 

 

The crater was well lit, but was close to being overwhelmed by moist air rising from the north-east. The road next to the observation platform was fresh-cut and revealed the recent stratigraphy.

The cinders here are being reclaimed by vegetation where the slope allows, and the outlook from the crater is greener than most of Gran Canaria, so observing succession here could be interesting.

From nearby pines Teide on Tenerife stands out well, as does new growth in the cinders after recent rains!

The crater can be seen from the top, as above, but there is also a viewing point from GC-70 at a lower level.

Hopefully the well-grown, if not giant, trees will give a suitable indication of scale.

Whilst travelling in the centre I noticed a pair of volcanic features; the unearthed layer of lava, looking very much like perched erratic, and a resistant dyke crossing the steep grain of the country.

Caldera de los Marteles

 

 

The caldera, below, is within an area of recent eruptive activity, as seen in the hills above the feature.

The Caldera de los Marteles appears a good half mile across and has a very flat and cultivated floor.

 

 

 

 

The spine of a  volcanic dyke runs down the steep slopes of the caldera's rim.
