The first found fragment, a stone weighing about Script error: No such module "convert"., was discovered by Sarah Sherlock Script error: No such module "convert". south of Homestead.[3] The area was wooded and covered by snow, impeding recovery efforts. On 10 February a Script error: No such module "convert". snowfall blanketed the ground, preventing the great majority of the fragments from being discovered until spring.
