Glen Providence Park, the oldest park in Delaware County, PA, engages in streamside buffer plantings on Earth Day every year. These native trees, shrubs, ferns, and perennials, along with limestone blocks brought in from outside the area, help to stabilize the stream bank and control serious erosion. This project also creates a riparian buffer, improving wildlife habitat and water quality.

From the Museum's website  --  The Earth & Mineral Sciences Museum at The Pennsylvania State University in State College is a unique mineral museum. The main gallery display includes displays of fine minerals such as azurite and "velvet" malachite from Bisbee, Arizona, and amazonite crystals from the Pikes' Peak, Colorado, area. The country's most extensive collection of paintings and sculpture depicting mining and related industries is on display in the Museum. 

Additional displays focus on plate tectonics and meteorological events.

The Museum is located on the first floor of the Deike Building at the Penn State University Park campus.  The Museum is open Monday through Friday, 9:30AM to 5:00PM, and admission is free.

Antes Fort was once a colonial outpost in Lycoming County, near Williamsport. William Penn's agents had bought the land from Andaste Tribal Chief King Wi-daagh.  Wi-daagh realized that for the few trinkets he received in exchange for this sacred site, he had been swindled by the Englishmen. Many report that Wi-daagh's spirit still roams the Nippenose Valley as a form of eternal protest.

A granite column from the Pennsylvania State Capitol was placed here to honor King Wi-daagh along the banks of Antes Creek in 1900, commemorating the treaty.  The column was originally part of the State Capitol building in Harrisburg that burned in 1897 and was transported to this location by the property's owner.

The back side of the column is engraved with the following:

WI-DAAGH
