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.

acorns in a plash of water
- Acorn: the typically ovoid fruit or nut of an oak, enclosed at the base by a cupule.
The acorn, or oak nut, usually contains a single seed (rarely two seeds), enclosed in a tough, leathery shell, and borne in a cup-shaped cupule. Acorns vary from 1–6 cm long and 0.8–4 cm broad. Acorns take between about 6 and 24 months (depending on the species) to mature.
Acorns play an important role in forest ecology when oaks are the dominant species or are plentiful. The volume of the acorn crop may vary wildly, creating great abundance or great stress on the many animals dependent on acorns and the predators of those animals. Acorns, along with other nuts, are termed mast.
Wildlife which eat acorns as an important part of their diets include birds, such as jays, pigeons, some ducks, and several species of woodpeckers. Small mammals that feed on acorns include mice, squirrels and several other rodents.
Large mammals such as pigs, bears, and deer also consume large amounts of acorns; they may constitute up to 25% of the diet of deer in the autumn.
Some animals, such as squirrels and jays serve as seed dispersal agents. Jays and squirrels that scatter-hoard acorns in caches for future use, effectively plant acorns in a variety of locations in which it is possible for them to germinate and thrive.
Even though jays and squirrels retain remarkably large mental maps of cache locations and return to consume them, the odd acorn may be lost, or a jay or squirrel may die before consuming all of its stores. A small number of acorns manage to germinate and survive, producing the next generation of oaks.

- Een eikel of een aker is de vrucht van een eik. Het is een noot met één, soms twee zaden. De lengte van een eikel varieert tussen de 1 tot 6 cm en is 0,8 tot 4 cm breed. Meestal duurt het tussen de zes en de 24 maanden voordat een eikel kiemt.
Afhankelijk van het weer vallen de meeste eikels in september en oktober. De hoeveelheid zaad die eiken produceren verschilt erg per jaar. Eens in de zoveel jaar, als de weersomstandigheden goed zijn en de bomen genoeg reserves hebben, produceren ze veel meer eikels dan anders. Deze jaren van overdadige vruchtvorming worden mastjaren genoemd.
Eikels zijn belangrijk voedsel voor dieren, zoals muizen, eekhoorns, wilde zwijnen, hertachtigen, sommige eenden en andere vogels en beren die in de buurt van eiken leven. Bij deze dieren bestaat soms 25% van de wintervoorraad uit eikels. Eikels werden vroeger gebruikt om varkens te voeren (mast).
De eik is voor het voortbestaan vooral afhankelijk van de gaai en van de eekhoorn. Een eikel valt niet ver van de boom en kan onder het bladerdak van de boom niet uitgroeien. Hij is dus aangewezen op dieren om de eikel verder van de boom te verplaatsen. Eekhoorns begraven voorraden eikels voor de winter. Als een eekhoorn omkomt of de voorraad niet of onvolledig aanspreekt of vergeet, is dat een ideale plaats voor de eikels om te kiemen.
Gaaien, zoals ‘Vlaamse gaaien’ officieel heten, zijn echte verzamelaars. Van eikels wel te verstaan. Ze leggen er een wintervoorraad van aan. De gaaien nemen de eikels mee in hun keel en stoppen ze een eindje verderop onder de grond. Een enkele gaai kan in het najaar zo duizenden eikels verstoppen. Gedurende de winter zoekt de gaai zijn voorraadplekken op. Zelfs in het voorjaar worden jongen nog gevoerd met ontkiemde eikels.
Je ne sais pas ce qu’il en est pour vous, mais, pour ce qui me concerne, je suis incapable de prévoir l’intérêt que pourra susciter (ou non) une de mes photographies… C’est un peu gênant quand on veut partager, faire un cadeau…
« Waouh » ou « bof », c’est toujours la surprise… Peut-être est-ce normal...

The Southern Giant Petrel (Macronectes giganteus), also known as the Antarctic giant petrel, is a formidable seabird native to the Southern Ocean. It is among the largest members of the Procellariidae family, with a wingspan of up to 2.1 meters and a body length of up to 90 cm. This species exhibits two distinct color morphs: dark and light. It is an opportunistic feeder, voraciously scavenging on marine mammals, other seabirds, and fish. It is often seen trailing fishing vessels to feed on discarded bycatch. The petrel breeds in small colonies on subantarctic islands, laying a single egg per season. A remarkable defense mechanism is vomiting a foul-smelling stomach oil when threatened, which deters predators and has earned them the nickname "stinkers" among sailors.

Tower cranes fill the Dublin skyline. These are part of the development at the old glass bottle factory site in ringsend. This site has been left empty and derelict for nearly 20 years. It’s great to see it being developed. It’s only a stones throw from the city centre.

Only when the last river has been poisoned,
Only when the last fish has been caught,
Then only will you see that money cannot be eaten."

It's easy to sit and remark at the olden days of the Pacman SD40s wishing that era would return but quite frankly, these SD40 ECO rebuilds are just awesome. Who doesn't like flared radiators? Here's K50 heading down to Dubuque coming from Marquette
in bonsai
there is a shaping wind in the hand
it flows from thoughts
from a vision
it flows for a lifetime
yet the bonsai is never complete...
when that lifetime ends
the bonsai may pass to another hand
perhaps the thoughts the vision
merge with that hand
perhaps they diverge
perhaps this continues
for several lifetimes
yet the bonsai is never complete...
it is complete only when
every molecule of the bonsai
has returned pollenlike to the ether...
eventually
a single molecule may reappear
it may reappear in a vision
it may reappear in a hand
it may reappear in a wind

This is a photo I took a long time ago. It had a lot of backscatter and was really dark, so I touched it up.
As a former science educator and education writer, I was fascinated by a stern-wheel steamboat in the Delaware River offshore of New Hope, Pennsylvania. The SPLASH is an authentic replica of an 1880 steamboat that operated in this area.
SPLASH is an acronym of "Student Participation in Learning Aquatic Science and History". The idea is that student groups use the boat during the summer season for onboard lessons in ecology, pollution sources, water quality testing, river organisms and local history (George Washington's famous 1776 Delaware River crossing was about 7 miles south of New Hope.)
SPLASH docks and sails from Lambertville, New Jersey, but is on the Pennsylvania side of the river in this picture.

An estimated $12.95 million worth of wild life animal skins were burned during the 2006 Tibetan New Year festival. Tibetans use animal skin for the decoration of traditional dress.
As a result, millions of dollars worth of animal furs and skins were destroyed as a pledge of sorts. Some say Tibetans in Tibet are advocating a clean environment and loving animals as per the Buddhist way of life.
From an environmental point of view, religion has been a positive and successful force influencing the relationship of Tibetans with their environment. But from other perspectives, religion can be seen as promoting dogmatic behavior with little long-term understanding. The majority of Tibetans have never learned about the environment, nor the ecological science and doctrine behind it. Tibetan Ecology Foundation wants to more deeply explain environmental science to Tibetans and rest of the world by publishing Wild Tibet: Tibetan Mammals and the Landscape of the Tibetan Plateau.

Sand dunes border the beach at The Pinery Provincial Park in Ontario, Canada.
Pinery Provincial Park was initially reforested with red and white pine trees giving the park its name. However, the area is not naturally a pine forest; the natural ecology is a very rare oak savanna. Only later was the true value of the natural ecology recognized, and the health of the oak savanna is now promoted.
Check out an album containing more of my photos shot in 2000.

Vine Street Expressway
The street lights around the Vine Street Expressway onramp at 21st St are favorite perches from which the Parkway hawks scan the rodent-rich scrubby verges of the crosstown highway. The field of road ecology, which studies the ecology of transportation infrastructure, was founded by R.T.T. Forman around the turn of the century.
5 exposures of +2, +1, 0, -1 and -2 made up this HDR image.
Used autobracket feature of Nikon D200 (can go up to 9 exposures in one burst).
The HDR treatment I used here is to reveal a realistic image rather than my usual artistic HDR style. Some HDR afficionados call it True Tone HDR or TTHDR for short.
Hope you like it.
