Hello Rowena - I can't really say what those rocks might be - and even a picture might not do it - but if you send a photo, we'd be happy to look. Thanks, Cheryl -------- Rowena Manuel wrote: My sis said that she found some unusual pebbles glued together on a beach in Ninilchik in 1964. They are glued in the center but they stick out around the edges. There were very few rocks like that there and she collected one sample. The rock's colors are redish and blackish and they are smooth. Her friends are saying that she could not have found them there. We could send you a picture, if you wish. We would like to learn how they came about being on that beach and how they are formed. You would settle an on going argument. Many thanks. -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
