I will say that yes, JPG images do deteriorate onver time when saved incessantly. Convert them to lossless TIFFs when storing.....
Other than that, rather than go into debateable guessing games I will offer this simple solution.
The sky in this kind of scene is more often than not, superfluous so don't include it when shooting. Besides, skiies and foregrounds differ so much in exposure needs that including both needs some really clear thinking on the photographers part and a good knowledge about possible outcomes.
If you don't like the attached, then discard it. If you do like what it is suggesting to you, then print it or keep a copy on your desktop while you modify your own original, which must be better than this, or why would you want to keep it - sentiment perhaps. Do so though, after changing your original file's format to TIFF first. Post processing can be a winner when the original composition is not up to par.

Thanks for your comments and constructive way of dealing with the problem. The picture is not what I consider a great one to save, nor am I particularly attached to it. I just wondered what on earth had happened to it.

I don't have an exact answer to your question, but I can tell you that it was not caused by moving or copying just like Ernie said. No file of any kind will ever degrade just from moving or copying it..including jpegs. When you move or copy any file to any other location, your operating system creates an exact copy, the data is exactly identical...it will never change or degrade..not in the slightest..the moved or copied file is an exact match of the original, and will always be....I know that's not what you are wanting to know, but feel free to copy or move files to your hearts content...no harm or degredation will ever happen..(unless your destination media is somehow corrupted)

Very misleading information 'achammar'. Saved files, eg, open and save to another location as I suspect some were in this thread, may deteriorate if filed in a lossable format. JPG files are hazardless if being changed from one location to another. Some people I have helped, used to open files as they were "moving(?)\transferring' them, and saving after viewing to the new location.
It is most important for the learners or the inexperienced to understand that JPEG files can detiorate. Better to be sure than sorry!
As to the photo concerned, a useful piece of advice would have been more welcome. The photo concerned is not a good package of data anyway and there are a lot of reasons why this one is not satisfactory as the OP would like, if for no other reason than old images would often have been produced on older hardware with inferior light capturing/handling abilities but, no matter, knowing that a JPEG can lose data while transferring them to other locations, no matter by what method, is more important than being given the impression that they can't.

rts2568 - You are saying (in a very kindly manner) the picture is rubbishy. I entirely agree with you. I was trying to get the hang of my first real digital camera at the time, and shot anything and everything in sight. If there were a competition for the worst composition, exposure and focus this one would not win, but I have quite a few serious contenders from those early years. Notice the filename is 0001 - this was the very first pic I took using the Finepix f401 (which I still have but don't use anymore.

Both are right. It depends on how you "move" the files. If you use "Save as" to a new location jpegs will deteriorate. You recompress the file.
If you just copy (copy and paste or move) a jpeg from one location to another it will not deteriorate. It makes an exact copy.
Ten years ago, did I "Save As" or did I copy/paste or drag? Difficult one. I hope I dragged as I do now, but certainly would not swear to it. in ten years I've probably had about ten computers and three or four external drives.

You say the image was never PP'd, could you possibly have forgotten that is was retouched at some point years ago? The reason I'm asking is because I'm totally confused how the treetops on the left side are darker than the leaves below them, also this shows in a few more smaller places along the tree horizon and appears to be an attempt to mask the sky area. The white in the sky is a complete washout, I downloaded the file and used a 0% tolerance mask and it chose the whole white area, meaning there are no variations in this whole area. The file seems to be missing color depth all across the spectrum, there are no smooth transitions of color anywhere but that cannot be caused by just copying and moving a file from one storage device to other. You may have used a program that "saved" a copy of the original each time you opened it or you may have just used "Ctrl-S" each time you opened it and closed it, saving jpg's will deteriorate with each new "save" but copying the original only duplicates the 1's and 0's of a digital file and in no way causes any deterioration or changes to the file. Don't just take my word for it, I've only worked with digital images of every major format in my business for 24 years, and I can pull up jpg's that I have moved from computer to computer through hard drives, flash drives, cd's and floppies and the files are exactly the same today as they were years ago.
Definitely no PP, I only started making "improvements" and repairs two years ago, and always save as TIFF or PSD. However you have sewn an idea which MIGHT explain something. I used to use the Fuji viewer to load pics. from my camera to the computer. Although I have no way of checking now, I am wondering if there was some form of applied preset on import.
