Signs on roads and footpaths around Nisyros point to ‘The Volcano’ in English and in Greek. Arrive by boat in the harbour and you are offered coach trips to The Volcano. A bit misleading that because by the time you arrive you are already standing on it. The whole island is a volcano. Or more strictly speaking, it’s part of a very much larger volcano which blew its top many years ago when it encompassed what is now Nisyros and the western end of Kos, the sea between being the now submerged caldera.
The ‘remnant’ volcano of Nisyros is classed as potentially active and is still grumbling away. Thermal springs emerge around the island at places such as Mandraki’s Hochlalos Beach, Avlaki, Palloi and the medical spa at Loutra. Indeed Hippocrates, he of the oath, sent patients from Kos to the spring in a cave in Palloi, also used by the Romans.
What is referred to as ‘The Volcano’ is the Stephanos crater at the western end of the 3 kilometre-long caldera, adorned by a coach park and taverna, but there are a number of other smaller craters and active hotspots nearby. The main caldera, Lakki, is the most seismically active but there are a number of smaller apparently dormant calderas including those at Nifios, Kato Laki and two between Siones and Evangelistra.
These calderas offer some of the most diverse and spectacular trekking I know, much of it on ancient routeways because the immensely fertile volcanic soils meant the island was once very densely populated. Old pathways and kalderimia link ancient settlements, habitations, chapels and monasteries. It’s a great pleasure to revisit old favourites and discover ‘new’ routes.
This year much of my walking focused on the main caldera and the active craters, old pathways going around much of the caldera at a high level with kalderimia zigzagging down to the caldera floor from the villages of Emborios and Nikia, and the monastery of Agios Stavros perched on the rim.
I am a self-confessed ‘vrachophile’, a neologism derived from the Greek βράχος (vrachos) – a large mass of rock, and φίλος (philos) – friend. Sounds so much less suspect than petrophile, πέτρα (petra) being a stone or small rock. I don’t go around hugging rock, certainly not when there may be anybody looking or unless I’m climbing, but I’m fascinated by them and do go around photographing them. Repeatedly. Obsessively.
This blog is about rocks around the caldera on Nisyros not from a geological or geomorphological perspective but aesthetic, a fascination with shape and texture, imagination running riot.
The whole of the island is made up of volcanic rock varying from famously hard black obsidian to very soft off-white pumice. Some of the most spectacular features are lava pinnacles, thrust upwards during eruptions and sculpted into fascinating and weird shapes by gases exploding out of them.
Drop down to the caldera floor from Nikia and turn west towards the Stephanos crater and cross barren desert to reach a ‘hotspot’ with bare rock heavily coloured by sulphur and fumaroles encrusted with needle-like sulphur crystals formed as boiling gases emerge. The surrounding rock is heated not only by the sun from a cloudless sky but by the underground furnace that is the magma chamber. It’s too hot and sulphurous to linger long but it draws me back time after time.
Another ‘grand tour’, Barry, informative and entertaining in equal measure… Good to get a sense that the travails from the earlier part of the year are well behind you.
Don’t know if you recall (back in July, on Symi) my Mac’s having having been hit amidships by best part of a pint of lager in the wake of a freak gust of wind during one of the Sunday evening movie screenings (no, not Poseidon Adventure, as it happened…); to cut long story short, one very sick machine eventually released from intensive care, saved from a – literally – sticky end, but am only now trying to pick up the online pace again. Anyway, I appear to have salvaged a couple of photos from the walk we did to the ‘deserted village’ above Pedi and wondered as to what might be the best means of forwarding these on to you?
Look forward to catching up with you again should our paths/kalderimia cross on Symi next year- in the meantime, best wishes for all your own outward-bounding.
