As we wake on Day 4, a beautiful view of Kibo is the backdrop for our camp.
Our 4th day will see us trek a rather short distance to our camp in Karange Valley. We will cover no more than 5Km, however we will have to scramble up some 400m up a massive wall called the Great Barranco Wall or the Breach Wall.

It is difficult to provide a sense of scale for this wall, but on this picture there are actually porters and other teams already making the harduous climb....
...upon a closer look you can see trekkers slowly inching their way to the top.
This day again begins under a bright and beautifully clear sky. This day we leave a little late, departing camp by 9:10. We know this day will be short, but I am somewhat apprehensive at the scramble ahead. As we start though, we begin with a very pleasant and slow decent amongst the now familiar Senecio.
Kibo is obviously much closer as we now head for the Great Barranco Wall.
From the face of the Great Barranco Wall we look down into the distance and see a beautiful 2 stage waterfall.
The hike up the Barranco Wall is strenuous but perhaps this leg was hardest for Nancy. For the past few days, she has been suffering from nausea. This prevented her from eating well and as a result her energy was greatly depleted by the time we made it half way up the wall. Needless to say, this was a very temporary problem for Nancy because in the end, she had no difficulty making it to the summit.

As we reached the top of the wall, we got a slight respite before a final climb. This was welcome relief as my quads were really starting to feel the climb.
Just a little further.....
....and we're almost there!
From the top of the Barranco Wall at over 4230m, we then gently decended into a desert-like valley (3940M) and back up to our camp at Karranga at an altitude of 4040m.
We now have a real sense of being on the slopes of a volcano.
We arrived at camp rather early (just after 1:30PM). After a hearty lunch, by 3:30, we headed off for a quick 1 hour acclimatization hike (to about 4150m) following the trail we would take the next day.
As night falls, we are obviously getting much closer to our target.
