Nope. There is not only one vanishing point. There is an infinite number of them.
You are thinking in terms of a cityscape where we have orthogonal walls. Each wall has its own set of vanishing points.
But when you have a natural organic landscape you do not have clear angles, so forget about them. That is why you do not see clear vanishing points.
A segment of the ice has one until it changes direction, until it changes size, until... it is better not to think on segmented vanishing points at all...
Let's imagine there are some towns on the horizon. If I choose to build a road for them, I would build a road with parallel edges. But as you can see I can build different roads, each with its own perspective.
The yellow and the red lead to the same town, but they have a different perspective. The red one looks as if the camera is lower on the ground.
The orange and the blue leads to different towns on the horizon. And all of them could be feasible.
We are used for a two-point perspective because we live in a rectangular constructed world, A room, a table, a city block. We are used to having parallel lines.
So let's try to put a rectangular base, probably for a small building.
The (A) image does look odd. Let's find out why.
We are assuming that the horizon is flat. If I draw some perspective lines to the horizon and one of the 90° border (closer to the camera) we can see that the other two are off (B). We simply need to correct them (C)
But this does not mean that they are the only vanishing points.
Here is a different perspective with different vanishing points with different "focal lengths" and the plane is really on the ground based on its own arbitrary vanishing points.
So. There is not only one vanishing point. There are endless ones. But you can only apply them to two (or more) parallel lines. Once you establish an artificial construction, the vanishing point will only work for that construction or additional constructions that use the same parallel lines.
As in nature we do not have intentional parallel lines there are no defined vanishing points, or there are a lot of undefined ones... The only line you have is the horizon, the rest of the grid is not defined.
Some exceptions could be a series of straight trees. They can be in fact parallel, so if you have an aerial shoot, or a shot inside the forest upwards, you can have one finishing point.
Light rays from the sun on a forest or thru the clouds can be also vanishing points, but only for the position of more rays, not the overall landscape.
One option is to imagine a 1 point perspective that feels right. You have the horizon, sometimes not too clear because you could have a mountain hiding it, but feel the overall sensation on where it is.
From there "feel" how high the camera is, based on whatever elements you have in the scene, how the trees are diminishing in size, imagine if the grid you are constructing "fells on the ground". Now the perspective will not match the individual elements, but at least you have defined some basic rules.
In the next images, the height of the camera is different, so you need to choose which one feels better for you.
