The last 22 sands were sent by Pete Gigliotti and they have just been entered into World Atlas of Sands database. Among them there are samples from 10 different states in the US (8 sands from Hawaii only, including the famous green olivine sand from Papakolea beach) and one sand from each British and US Virgin Islands. Thanks much Pete for this trade!
