If you're wondering what sorry if situation allowed for quicksand 

I used to teach kids how to ride horses and give trail rides. One dinner there was a fire on the mountain. The next year will the trails were 6ft higher then they used to be because so the ash came down from the mountain in the rains over the year. 

When it rained that turned into mud and if you weren't careful you'd be up to your hips or worse. I had a lot of horses get stuck and we had to pull them out with a tractor. 

Smelled like peanutbutter chocolate milkshakes🤷🏽
