Think of it this way: when listening to a friend telling the story of an experience he had, what is more interesting and keeps you glued to what he is saying, a detailed, nothing-left-out, inch-by-inch chronology of every waking moment he had, from what time he brushed his teeth and chewed his oatmeal to which rock he sat on for lunch and how many times he swigged water from his bottle to which side he placed his walking shoes outside his shelter and how many minutes his headlamp was turned on before he went to sleep... or, a series of quick sketches of the best moments of his trip, with some emotional structure that gives the story a human element?
For instance, (and please don't feel offended at this example, just trying to show you how an editor sees things), a little down from the top you have the picture of your blue windbreaker clad friend at the picnic table taking out a Caldera stove, then the next picture is of the same blue clad friend also with a Caldera stove, then a picture of the BushBuddy, followed by the blue clad friend with the Bushbuddy again and then another table shot of the table with a stove, then the iPod, and only then finally a different type of shot with the net shelter, and on to two almost identical shots of your friends stopping to take a break. Look at the run of these shots and mentally eliminate any of them that essentially show the same image. You could eliminate at least 1/3 of the shots and still say exactly the same thing.
Many of your pictures are of three people walking along the trail or resting. Of course, since this is a backpacking report you want to show people actually backpacking, but it might come across stronger if each image stands out as an instance, while at the same time reflecting onto the next image, enhancing it.
Landscapes are wonderful (I love landscape photography), but readers almost always respond more powerfully to images with humans in then... our herd instinct, I guess.
Nevertheless a great story to follow!
I'm not saying at all that your story is boring (I'm enjoying it!), but just trying to both explain how editing works and how you can save yourself a lot of preparation time. Editing is a lifelong art and takes many years to develop well. One of the great losses in great writing is the loss of editors on the internet; many great writers became great due to the invisible hand of their editors. A good editor is just as important as being able to write well.
