Lake Huron Puddingstones

Puddingstone, also known as Jasper Conglomerate, Pudding Stone, Lorrain Conglomerate, Quartz Conglomerate, Plum Puddingstone is a rare conglomerate found in only a few places in the world. Puddingstone was named by Cornish miners who thought the stone resembled their traditional Christmas pudding made with raisins, cherries, currents and nuts.
In Michigan, in Lake Huron, St. Joseph and Drummond Islands produce a distinct Puddingstone. This stone forms in a semi-transparent quartzite, sandstone matrix. The matrix, background, main rock is usually white, cream, sandy but can be a wide variety of colors with pinks, greys and browns included.
The inclusions, pieces of imbedded pebbles & stones, can vary as well. Jasper, from bright, lipstick red to browns, purples, oranges and pinks, is the main inclusion. Other minerals could be quartz, chert, hematite, black flint, green quartz, and even fossils.
This journal is my research into the wonders of Lake Huron Puddingstone.

More Places to Find Puddingstones


I was weeding, at my church, when I noticed the distinct patterns and red jasper of Puddingstone. Within a half hours time, I has collected these medium to small ones.
 I has my church's permission to collect the Puddings and I replaced what I took with an equal amount of rocks from my stone piles at home.
