What you are seeing here is something called “candle ice,” named after the tiny candle-like structures the ice is shaped as.
Candle ice forms when the ice is ready to break down. Solar energy begins melting the ice from above, and the weakest portion of the slab is located on the boarders of the ice crystals inside the slab. Sun and water work together to erode away along these impurity lines, creating pillars from the slab.
Candle ice is very unstable, often shattering with very little external force. While it is unsafe to walk on without solid ground below it (as seen in this instance here) it can be very fun to break apart by hand on a warm spring day.
