 The erupting Great Geysir Geysir (sometimes known as The Great Geysir), in the Haukadalur valley, Iceland, is the oldest known geyser and one of the world's most impressive examples of the phenomenon. The English word geyser to describe a spouting hot spring derives from Geysir (which itself is derived from the Icelandic verb gjósa meaning to erupt. The English verb gush is probably related to that word). Geysir lies on the slopes of Laugarfjall hill at 64°19′0.05″N, 20°17′59.64″W, which is also the home to Strokkur geyser circa 400 metres south.

Eruptions at Geysir can hurl boiling water up to 60 metres in the air. However, eruptions may be infrequent, and have in the past stopped altogether for years at a time.
History
The oldest accounts of a geyser at Haukadalur date back to 1294. Earthquakes in the area caused significant changes in local neighbouring landscape creating several new hot springs. Changes in the activity of the Geysir and the surrounding geysers are strongly related to earthquake activity. In records dated 1630 the geysers erupted so violently that the valley around them trembled. For broader historical context, see 1290s and 13th century. ...

In recent times earthquakes have tended to revive the activity of Geysir which then subsides again in the following years. Before 1896 Geysir was almost dormant before an earthquake that year caused eruptions to begin again, occurring several times a day, lasting up to an hour and causing spouts of up to 60 metres in height. In 1910, it was active every 30 minutes; five years later the time between the eruptions was as much as six hours, and in 1916, the eruptions all but ceased. In 1935 a manmade channel was dug through the silica rim around the edge of the geyser vent. This ditch caused a lowering of the water table and a revival in activity. Gradually this channel too clogged with silica and eruptions again became rare. In 1981 the ditch was cleared again and eruptions could be stimulated, on special occasions, by the addition of soap. Following environmental concerns the practice of adding soap was seldom employed during the 1990s. During that time Geysir seldom erupted. When it did erupt, it was spectacular, sending boiling water about forty metres into the air. On the Icelandic National Day authorized government geologists would force an eruption. A further earthquake in 2000 revived the geyser again. Initially eruptions were taking place on average eight times a day. By July 2003 this activity had again decreased to around three times per day. Year 1896 (MDCCCXCVI) was a leap year starting on Wednesday (link will display calendar). ...

The nearby geyser Strokkur erupts much more frequently than Geysir, erupting to heights of up to 20 metres every five minutes or so. Strokkur's activity has also been affected by earthquakes, although to a lesser extent than the Great Geysir. There are around thirty much smaller geysers and hot pools in the area, including one called Litli Geysir ('Little Geysir'). Strokkur, or The Churn in Iceland, is a geyser that is situated in the geothermic region beside the Hvitá River in Iceland at .

Litli Geysir, Haukadalur, Iceland Descriptions of the Great Geysir and Strokkur have been given in every travel guide to Iceland published from the 18th century onwards. Today the geyser remains an essential element of almost every tourist's itinerary. The place is, together with Þingvellir and the Gullfoss waterfall, part of the most famous sights of Iceland, the Golden Circle.

Ownership of the Geysir area
 A forest near the Geysir. Until 1894 the Geysir area was owned by a local farmer. In that year the area was sold to James Craig (later Lord Craigavon), a whisky distiller and future Prime Minister of Northern Ireland. Initially he erected large fences around the site and an entrance fee was charged for visitors wishing to view the geysers. The following year however Craig appeared to tire of his project and gave the area as a present to a friend, E. Craig, who dropped the entrance fees. Later Craig's nephew Hugh Rogers inherited the site. In 1935 he sold the site to film director Sigurður Jónasson who subsequently donated it to the Icelandic people in perpetuity.
