History of the telescope received the report in November, and the English mathematician and astronomer Thomas Harriot, who used a six-powered telescope by the summer of 1609 to observe features on the moon. The Italian polymath Galileo Galilei was in Venice in June 1609 and there heard of the "Dutch perspective glass" by means of which distant objects appeared nearer and larger. Galileo states that he solved the problem of the construction of a telescope the first night after his return to Padua from Venice and made his first telescope the next day by fitting a convex lens in one extremity of a leaden

The site is Crown Land, administered by the Department of Conservation, with help from the "Craters of the Moon Trust", a volunteer organisation that provides information for visitors and passive vehicle security. In 1859 Ferdinand von Hochstetter, an Austrian geologist who traveled through the area, reported a colossal column of steam from the Karapiti Blowhole (fumarole), observable from about 20 km away. It was difficult to approach because steam vents and springs covered the valley floor
