My story of reaching the top on 26th of March 2015:
I started to go up from the Refuge de Toubkal (upper hut) at 6:00 am with the crampons and protective gaiters already on and had amazing weather that day. It was clear, sunny and not extremely windy. I have reached the top at 8:45 with amazing views of whole Atlas mountain range, even a day before on 25th of March it was terrible weather and after 6 hours of unsuccessful ascent and trying to find the summit in crazy fog and unbelievable strong wind (60 km/h), temperature with the wind around minus 30 and I had to give it up and wait one more day what was at the end perfect scenario and I was lucky to see great views on the way to and on the top, sunshine was everywhere on the peaks!
The cache is hidden very close to pyramidal metal frame in the height of 4,165 meters. Originally as the container I have used what I found on the top, it was party popper tube. There was a little party obviously :) Later it has been replaced with lock n lock box.
