On Saturday I returned to Derwent Dam to check on the state of the exploded larch I discovered a year ago. Not a lot has changed.
Only fifty metres or so away up the hill was another toppled larch that I didn’t notice last year. This one didn’t look as if its demise was as explosive as the other; more of a folding than an exploding. Both prostrate trees are aligned in more or less the same direction: pointing uphill (south-east, I think). I reckon it most likely that they were just blown over in strong winds, perhaps even on the same day.

The imposing Derwent Dam. When the reservoir is full, as it was on Saturday, water pours from between the two towers to cascade foamily down the mighty stone wall.
A spot of super weather was forecast for Saturday so in the morning I headed off to Fairholmes, the visitor hub for the Derwent Valley. The weather didn’t live up to my high expectations, but it wasn’t too bad. At least it’s spring now; winter seems to have been abruptly switched off on the 28th of Feb. From Fairholmes I headed north along the western shores of Derwent and Howden reservoirs, before turning west and climbing up onto the moors to reach the spectacular Alport Castles. Following the high ground south-east, I eventually ended up back at Fairholmes. (Have a go at sussing it out on Google Maps!)
Horse chestnut (Aesculus hippocastanum) buds are amazingly sticky. This one has glued itself to a few stray conifer needles.
This brave young alder (Alnus glutinosa) was growing part-submerged in the reservoir.
The road running up the side of the reservoir is bordered for a few hundred metres by a hawthorn hedge. It has been recently savaged along most of its length, probably by rabbits. They have stripped the bark from most of the stems an inch or less in diameter; anything larger was left unharmed.
Illuminated fruticose lichens (and unilluminated foliose lichens) growing on sycamore (Acer pseudoplatanus) bark on the site of Tin Town. (For the fascinating history of Tin Town, or Birchinlee, see here and here.)
A fine beech (Fagus sylvatica) growing on the site of Tin Town – so it can’t be any older than a hundred years.
This is another beech, but instead of having the lovely, smooth, silver bark typical of its species, this tree was all over disfigured by cankers.
This is the tip of the westwards-pointing spur of Howden Reservoir where it is joined by the River Westend – and look! There is still ice on the surface in the middle of March!
Looking back at Howden, having attained the lofty heights of the moors. There were still plenty of snow pockets around up on the tops. It hasn’t snowed for weeks!
Almost back at Fairholmes – this is the view across the northern tip of Ladybower Reservoir.
Next month’s edition of the Festival of the Trees will be hosted by Vanessa of Vannessa’s Trees and Shrubs Blog. Send in your submissions to treesandshrubs [dot] guide [at] about [dot] com. The deadline is the 29th of March. (The optional theme, in honour of April’s Fools Day, is humourous trees.)

On the 28th of February 2009 – over a year ago! – I went for a walk around the Derwent and Howden Reservoirs. I saw something in a plantation on the hillside: it was an exploded larch.

Alders (Alnus glutinosa) in front of Derwent Dam.
Derwent Reservoir, in the center of the Peak District, has quite an unusual style of dam wall. Instead of the grassy embankments used to dam most reservoirs in the vicinity of the Peak District, the dam wall at Derwent (and neighbouring Howden Reservoir) is much steeper and faced with huge stone blocks. Large gothic towers loom at either end of the dam wall, and in wet weather, water overflows between the towers and cascades down the great stone wall in a magnificant spectacle.

During World War II, Derwent Reservoir was used for bombing practice by the RAFs 'Dambusters' (617 Squadron). The dam at Derwent was used as it was of a similar design to those in Germany's Ruhr Valley, which were to be the target of RAF bombing raids; with the dams destroyed and the reservoirs empty, it was hoped that German industry would be seriously impeded and thus their war effort hampered.
Rowan a.k.a. mountain ash (Sorbus aucuparia) in front of Derwent Dam.
The barrel-shaped 'bouncing bombs' used by the Dambusters were designed by Barnes Wallis. The bombs were dropped spinning rapidly backwards at a low altitude in order for them to bounce over the reservoir surface to reach the dam wall. They would then spin downwards to the base of the wall before detonating.
Scots pine (Pinus sylvestris) in front of Derwent Dam.
I visited Derwent Dam this afternoon and took these photographs. Thanks to the recent very wet weather, the water rushing down the dam wall made for a very impressive sight.
