Exploring the woods of the Adirondack Mountains, this gelatinous blob was found near the edge of standing water on a logging road. The entire length of this thing is probably just under 10 inches and it seems to be about an inch thick (didn't measure). The road was used about a year ago, maybe more, and has existed for quite a while. The puddle doesn't really drain, so it's there most of spring and whenever there's a lot of rain.

woods gloop

There's not much human activity around this spot. Upstream of it is more forest for many miles. Of course being a logging road and a place where a photo was taken, there is some human influence and potentially petrochemicals introduced.

What could this blob be?

My first guess is poop but that doesn't seem to be the case because from what I've seen with dog poop it gets liquefied and dispersed by rain and water, not turned into globs like this. Beyond that, I have a hard time making any concrete guesses. A mountainous jelly fish? Maybe some kind of bio-chemical reaction from a few different 'ingredients' in the puddle?

    It could be an egg sack from an amphibian.

    The image doesn't show the black spots that would be a dead giveaway, but it looks like a mass of wood frog (or other amphibian) eggs. See: natureintoaction.com/2008/03/14/virginia-vernal-pools-program/…

    The bottom right "blob" appears to have a few spots inside. It might be from a salamander.

The pool of water they are in is called a vernal pool. Amphibians and other woodland creatures take advantage of these temporary pools while they last.

Not having anything for scale in the picture, they appear to be salamander eggs similar to those shown on this site:

    Wow, cool! I knew amphibians like these kind of vernal pools but had no idea what their eggs looked like and for whatever reason assumed they don't look like this. So as @DonBranson commented, these globs are likely protein sacks containing eggs?
