The Needles vehicles transporting disabled visitors. This is because the single track road's position close to the cliff edge is considered dangerous for multiple car use. The Isle of Wight Coast Path has its westernmost point at the Coastguard Cottages. The Needles' pointed shape is a result of their unusual geology. The strata have been so heavily folded during the Alpine Orogeny that the chalk is near vertical. This chalk outcrop runs through the centre of the Island from Culver Cliff in the east to the Needles in the west, and then continues under the sea to the Isle of Purbeck, forming
Faint Images of the Radio Sky at Twenty-Centimeters the FIRST Bright Quasar Survey (FBQS), which comprised quasar candidates that were then followed up with optical spectroscopy. The initial survey found 69 quasars, with 51 being newly identified. A number of broad absorption line quasars were discovered by FIRST. Other, high-redshift quasars were identified in the survey by cross-matching with SDSS. Variability was detected in over 1600 sources during the course of the survey, including stars, pulsars, galaxies, quasars, and unidentified radio sources. On large scales, the two-point correlation function between radio galaxies was observed. Faint Images of the Radio Sky at Twenty-Centimeters Faint Images of the Radio Sky
