Kilimanjaro is a gigantic stratovolcano with three distinct volcanic cones. Three cones are Kibo, Mawenzi, and Shira, Kibo being the highest. Uhuru Peak on Kibo at an elevation of 5,895m is the tallest point in Africa and is the place that trekkers most aspire to be.
Although the inside of the cones are obscure due to the absence in erosion. The outside part of the cones is packed with snow. It's composed mostly of layers of solidified volcanic lava, with a few pyroclastic rocks that are typical in volcanic regions. A continuous eruption for thousands of years ago has buried the majority of older geological features, apart from the stratum that is a sedimentary rock.
Weather conditions in Mount Kilimanjaro are heavily dependent on the height of the mountains, equatorial trade and trade winds that are anti-trade. Downslope and upslope winds are prevalent in the mountains and you'll always be blasted by them, no matter where you are located, with the southern part being more intense than northern.
Two distinct seasons of rain. The first is from March through May, while the other is between November and. The lower regions on the south slope get more rain than the northern regions and are more lush. In addition to the season of rain it is usually dry.
The thing to be aware of is that there are five climate zones that you'll come across when you climb towards the highest point. They include rainweald, bushland, Heath and Moorland, Highland Barrens, and IceCaps. The order of these is between low and high with bushland being the lowest, and IceCaps being the most high levels.
