Green Lakes State Park's outstanding features are its two glacial lakes surrounded by upland forest. Both Round and Green Lakes are meromictic lakes, which means that there is no fall and spring mixing of surface and bottom waters. Such lakes have a high potential for evidence of ancient plant and animal life.
