Limonite iron ore. Limonite is a yellowish-brown iron ore and was the most important source of iron for the iron and steel industry in the Lehigh Valley during the 1800s and early 1900s. The abundance of anthracite coal from the northern portion of our area helped fuel the blast furnaces used in the production of iron and steel during this time.
