Lady Know Geyser: This geyser, located at wai-o-tapu (sacred water), was discovered in 1901 by prisoners. These newly relocated prisoners were allocated the job of clearing and planting pine trees. The prisoners used the geyser to wash their clothing when they found out that they could make the geyser erupt by adding soap. The cone shape of the geyser was formed by silica accumulating on rocks placed around the geyser base to make the water spray higher. The natural eruption cycle is every 48 to 72 hours, however, when artificially induced it erupts daily at a designated time. The geyser is caused by a heated reservoir underground comprised of 2 chambers. The bottom chamber is 150 degrees C and the upper chamber does not exceed boiling. The upper chamber acts as a lid to keep the hot water down. When soap is added, it softens the water in the upper chamber and it mixes with the lower chamber causing an eruption that can reach up to 20 meters and last for up to an hour depending on weather.
Fox Glacier: This glacier drains from Mt. Cook and flows toward the west coast of New Zealand. Characteristics of this glacier include the seracs or the towers of ice formed on top of the glacier and trim lines from former lateral moraines. There is also melt water at the bottom of the glacier that is produced from midglacial tunnels in the middle of the glacier. There is dead ice further down the valley that is evidence of glacial recession. Dead ice are blocks of ice that have been left behind by a retreating glacier and were insulated by the outwash debris. Occasionally glaciers can get clogged and when finally released it causes a huge flood. Surge glaciers happen when too much pressure builds up and force the glacier to move abnormally fast. This glacier is advancing due to accumulation of increased snowfall (ablation) which is shown by the layering of dust bands.
