Yesterday I went on first fossiling trip of the year. Its one of a pretty small timeframe in which I am able to accessible certain sites as thaws are happening but marshlands are frozen. Two years in row found a sizable agate in very different locations - last year was on a sandy road recently constructed up north Minnesota. This agate (right side) is hardly chipped. The left side is typical twin cities glacial deposited japser - certain sites far north Minnesota produces superior quality jaspers by compare. This one is much more smooth on one side and more redder than usual
