Озеро Гижгит находится в Баксанском ущелье Кабардино-Балкарии, недалеко от поселка Былым. Взглянув на озеро, сложно представить, что подобная красота является рукотворной, и к сожалению, даже таит в себе угрозу.
Строго говоря, озеро Гижгит совсем не озеро, а запруда одноименной реки. Дело в том, что в 1940-2000 годы примерно в 10 км от этого места рядом с г. Тырныауз действовал Тырныаузский горно-обогатительный комбинат (ТГОК), специализирующийся на добыче и обогащении вольфрамо-молибденовых руд. В 1966 году в русле реки Гижгит, которая является притоком бурной горной реки Баксан, для нужд ТГОК было построено третье (основное) хвостохранилище, или, если говорить проще, отстойник токсичных отходов производства. Устье реки было перегорожено плотиной, в результате чего в русле горной реки образовалось водохранилище, называемое сейчас озером. Сток воды из озера Гижгит осуществляется по специальному отводному тоннелю в реку Баксан.
Хвосты — профессиональный термин, обозначающий отходы производства руды, зачастую токсичные. Хвостами называют токсичные отходы обогащения полезных ископаемых, соответственно хвостохранилище – комплекс специальных сооружений, предназначенный для их хранения и захоронения.
В годы работы комбината в хвостохранилище по десятикилометровому трубопроводу поступали отходы обогащения вольфрамового, молибденового и медно-висмутового концентратов. Около 30 наименований химических соединений металлов, каждый из которых в сильных концентрациях смертельно опасен для здоровья человека и животных. По различным оценкам, с 1966 по 2001 год тут было захоронено от 25 до 118 млн кубических метров отходов.
В настоящее время трубопровод демонтирован, но отходы остаются в озере. Уровень воды в нем поддерживается при помощи сбросного колодца для водопонижения и водоотведения, связанного с водоотводным каналом, соединяющим озеро с Баксаном. Считается, что отходы на дне озера слиплись практически до состояния цемента.
В 2018 году на страницах научно-технического журнала "Вестник МГСУ" группой ученых (К.А. Гегиев, А.Х. Шерхов, З.Ж. Гергокова и К.К. Анахаев) была опубликована статья под названием "Экологические проблемы Тырныаузского хвостохранилища на реке Гижгит", в которой подробно описана опасность, исходящая от бывшего хранилища ядовитых отходов:
"В обогащенных отходах содержатся до 30 наименований химических соединений металлов (в т.ч. высокого класса опасности), которые с поверхности пляжа хвостохранилища в виде пылеватых облаков переносятся постоянно дующими вдоль долины р. Баксан ветрами (Тырны-Ауз в переводе с балкарского языка «ущелье ветров») на прилегающие к ним сельхозугодья и природные пастбища..."
Гижгит — река в России, протекает в Эльбрусском районе Кабардино-Балкарской Республики. Длина реки составляет 28 км. В низовьях запружена, образует водохранилище-хвостохранилище Тырнаузского горно-обогатительного комбината. В самом низовье протекает по искусственному тоннелю до места впадения в реку Баксан. Устье реки находится в 112 км по левому берегу реки Баксан.
The Falkirk Wheel is a unique boat lift in the world. It replaces a series of 11 locks linking the canals from Glasgow to Edinburgh. The Falkirk rotary lift has a diameter of 35 metres and lowers or raises ships to a height of 25 metres. A set of double doors allows the boat to enter on one side and to leave on the other side. The wheel turns the two caissons, each weighing 300 tonnes, while the gearing system keeps them perfectly horizontal.
This steam engine is a real vintage among vintages. Made by Fowler and Company in Leeds, England in 1880, it has been perfectly restored to its former glory. This is a close up of the engine that was pulling the trailer in my previous shot.

The daffodils and blossom do their best to brighten a dull Saturday morning. Engineering on the Stour Valley Line sees GBRf's 66755 trundle through Coseley with 6G56 from Basford Hall Yard to Dudley Port.
This is in the back garden of the house we have lived in for about 40 years, and this is first time I have noticed the manufacturer's name on the manhole cover (unless I've seen it before and forgotten).
One of the most vivid memories I have from my primary school years was visiting the Dover Engineering Works with my school. It's not surprising that seeing molten iron poured from a ladle into a mould from close quarters would make a lasting impression on a child. I can still see clearly in my mind the wooden pattern they had made of our school's badge being pressed into the compacted black sandy material in the mould. The pattern was then removed and the top half of the mould filled with more compacted material was fitted. Small holes to allow the escape of burning gas were made in the material. When the molten iron was poured into the mould, sure enough, jets of flame appeared from these holes. When the mould was eventually stripped, there was the grey/silver replica of the wooden pattern.
When the company was established in 1830 it was on the outskirts of Dover in the parish of Charlton, with a supply of water from the adjacent River Dour. Charlton has since been absorbed by Dover, and the engineering works is of course gone - with the site now occupied by a supermarket.
1940s (?) Keuffel & Esser (K&E) 4080-3 Log Log Duplex Trig slide rule. Before small, affordable electronic scientific calculators became popular in the 1970s, the slide rule was the workhorse of engineers and scientists everywhere.
For this picture, I set the cursor to the 2.25 mark on the A scale. The cursor position corresponds to 1.5 on the D scale, which equals the square root of 2.25. 1.5 is also the cube root of 3.375, the location of the cursor on the K scale.
Carquinez Bridges, and yet another perspective of these structures. My go to spot at 4am.
Shot with the tack sharp Nikon 70-200 f/4. Thanks for looking.
genetic engineering
could create the perfect race
could create an unknown life-force
that could us exterminate
introducing worker clone
as our subordinated slave
his expertise proficiency
will surely dig our grave
it's so tempting
will biologists resist
when he becomes the creator
will he let us exist
bionic man is jumping
through the television set
he's about to materialise
and guess who's coming next

66599 with a consist of wagons which always strikes me as looking like a phalanx of Roman soldiers with sheild's raised, ready to form a 'Testudo' or 'Tortoise' manoeuvre. Zoom in and you'll see what I mean hopefully.
Those wagons form the HOBC, high output ballast cleaner, at almost half a mile long, of which approximately half is in view here. It has just battled its way up Marshbrook Bank, south of Church Stretton, and will have a further climb over the South Shropshire Hills to Shrewsbury.
This was the scene behind my viewpoint shown in the previous upload of the Grid, waiting on the other side of the level crossing.
The yellow broom lineside made the perfect foil for those wagons. I repositioned and took another shot at Condover around two hours or so later.
It's 7.07am, and the Sunday engineers are preparing to leave the worksite, which appears to be between Dorrington and Marshbrook. This is the 06.00 Marshbrook to Crewe Basford Hall working, which has already run to Craven Arms to take the up line back to here, for the record, 66511 was assisting on the rear, 16.5.21.

My second entry in this months competition on Bridges.
Had a few days away in Bristol so couldn't really visit without seeing and taking an image of the magnificent Clifton Suspension Bridge.
It spans the river Avon and has a remarkable history which is well worth reading about.
The original design was of Isambard Kingdom Brunel .
Spanning over 702 ft and 249ft above the Avon it had the longest span of any bridge in the world at the time of its construction.
Thank you for viewing and any comments
