Yoho in colour, a Dickens of a fish – and who was Dolly Varden?

Dolly Varden – what a name! But who was she? Or, who is she? A mystery, or mysterious unknown person, at least to me. For a naturalist, it must be great to be qualified and knowledgeable enough to be able to identify and name a new species. How does that happen?

A sunny spring hike in Yoho National Park a couple of weeks ago had me pondering this as I came across a name I’d never heard before. Naming a new species? Maybe you have to be the first person there. Or the first person to tell someone else. How are the actual new names chosen? Do you name it for yourself, or for a nearest and dearest? (Best be careful here, a loved one might not appreciate their name being used for a new species of insect or mollusc – just saying). The place it resides? Or whatever comes to mind? I’m pretty sure there is a sound scientific method these days. Dolly Varden…

We’d intended to go snowshoeing as snow had fallen later in the day and overnight after we’d taken our monochrome Field pictures (A Field Day). Instead, the Rockies played their usual weather tricks, and freezing winter one day gave way to an almost summer like sunny day the next, with temperatures reaching double digits in the high teens.

On the way to Emerald Lake we stopped and took in the views up and down the Kicking Horse River as it kicked on in the early thaw.

  Beautiful looking upstream…

  …and beautiful looking downstream!

When we arrived at Emerald Lake, you could see the remaining snow on hiking paths was packed and easy to walk on without snowshoes. Of course, with spring temperature fluctuations, it was now avalanche season in Yoho, and this determined where we could hike safely. 

  Couldn’t miss – or ignore – the warning!

Jackets had to be removed, and no need for hat and gloves. It was so warm that butterflies were out! Best of all, you could breathe in pine fragranced air and hear almost total quiet – hushed enough to enjoy the occasional knocking of a woodpecker, the call of distant songbirds and the rush of wings as ravens flew overhead. Aah, spring. The path wound through trees and descended to the edge of the lake.

  Tantalizing views through the trees close to the lakeshore!

It was actually pleasant to be in the cool of the shade from time to time, although really it was even more pleasant to feel warm sun on your face!

Is it time to get back to the question at the heading of this piece? Yes it is, PlaidCamper! 

At intervals along the edge of the frozen lakeshore there were wooden signs providing information about the geology, flora and fauna around Emerald Lake. The rock flour or silt that is found in the water provides the beautiful summertime colour the lake is named for. Silt prevents much light penetrating the water and consequently there is relatively little aquatic life. However, according to the information, one of the larger fish species found is the (drum roll) Dolly Varden char. 

I was so intrigued by what seemed a strange name for a fish that I looked it up later. It comes from a Dickens character in Barnaby Rudge, who wore muslin over petticoats – a fashion in the late 1800s –  and the fish colouring and patterning is reminiscent of this. So, Dolly is a fashionable and literary fish! Probably better than naming it after a potential future ex…

It was such a delightful hike around the lake. We’d hoped for a blast of winter and were rewarded instead with a beautiful spring day. That, and making Dolly Varden’s acquaintance, made for a different mountain adventure. 

  Get it down, make it watertight, and go fish for a Dolly…

Now, I wouldn’t mind betting there’s a great recipe out there for Dolly – I’m thinking lemon, rosemary, and a hint of garlic. Any ideas?! Thanks for reading, and keep your guy ropes secure.
