Do you know what I'm describing?

[Leigha]

Over the weekend, I watched a random video having to do with frozen ponds, lakes, etc. I couldn't tell you the title of the video, or how I stumbled upon it. Wasn't paying attention, at the time. I didn't view the entire thing, but basically ...it showed a guy picking up small ice blocks from a frozen over lake, and dropping the blocks on the ground. The blocks would crack open into several pieces of what looked like, ice pick shaped rods. It was one of the most beautiful, yet unusual things I've seen happen in nature. But, I can't seem to find any information on what that process was. The results keep turning up ''falling into a lake,'' and ''how to survive falling into a lake.'' Not sure how to describe this, but does anyone know what I'm talking about? 

TL;DR:
What is the process called when ice blocks fall on the ground, and shatter into ice pick looking shapes?

I always thought that ice came in little cubes that you put in your drink.

But here's something that might be similar. They call it ice 'chandeliering'.

Wow, how cool is that! But, not what what I'm thinking. Maybe I'll run across that video again. There are a good number of ice ''shattering'' videos, but the key difference with what that specific video captured, is the ice shattered into stick like pieces. Like a deck of cards fanned out, the ice ''sticks'' were fanned out when the block shattered. It was really something.

If it was YouTube, check your history.

I watched it on YouTube, on my Smart TV and it doesn’t store vids as my phone does. Oh well. :/

Was it candle ice?

Yesss! This is it!! I’ll return later but just wanted to thank you!

And this explains it:

So ''clean'' ice is being replaced with decayed ice, which may be due to the problems associated with climate change. It feels wrong for finding it beautiful.

No. Candling is a natural occurrence that’s we’ve always had, and yes, it’s beautiful.

"In the spring, when average daily air temperatures rise above the freezing point, ice begins to decay. Two processes are active during this period: a dimensional thinning and a deterioration of the ice crystal grains at their boundaries. Thinning of the ice layer is caused by heat transfer and by melting at the top or bottom surface (or both). Deterioration, sometimes called rotting or candling because of the similarity of deteriorating ice crystals to an assembly of closely packed candles, is caused by the absorption of solar radiation. When energy from the Sun warms the ice, melting begins at the grain boundaries because the melting point there is depressed by the presence of impurities that have been concentrated between crystal grains during the freezing process. Rotting may begin at the bottom or at the top, depending on the particular thermal conditions, but eventually the ice rots throughout its thickness. This greatly reduces the strength of the ice, so that rotten ice will support only a fraction of the load that solid, unrotted ice will support. Thinning and deterioration may occur simultaneously or independently of each other, so that sometimes ice thins without internal deterioration, and sometimes it deteriorates internally with little or no overall thinning. However, both processes usually occur before the ice cover finally breaks up."

Oh, I was reading about rotten ice from the link you posted. It sounds like a natural occurrence stemming from “rotten ice.” I’m awed by the beauty of it, nonetheless. : )
