Fall Foliage Map 2018: When Autumn Leaves Peak In Maryland

MARYLAND — While it's officially fall, it will feel like summer this week in Maryland, but fall temperatures will inevitably arrive and leaves will soon change colors to blazing reds, vibrant oranges and sunny yellows. Exactly when will that happen in Maryland? You can’t know precisely, but there’s a tool to help you plan excursions around the dates when fall foliage should be at its most fabulous.

To get vivid leaf colors, we need crisp autumn nights, and Maryland isn't there yet, resulting in only patchy foliage colors so far. But summer heat and above normal rainfall this year should produce some stunning views, says The Foliage Network.

The Fall Foliage Prediction Map, found on the Smoky Mountain National Park website, includes predictions not just for the Smokies, which rise above the Tennessee-North Carolina border, but for all 50 states. In Maryland, fall colors are expected to peak around the week of Oct. 22, although it will happen sooner in western Maryland.

Our state offers some stunning vistas, including several in state parks suggested by Visit Maryland:

• The C&O Canal National Historic Park offers numerous hiking options, such as the strenuous Billy Goat Trail for advanced hikers. The trail rewards hikers with vistas of the surging Potomac River flanked by forests bursting with color.
• Elk Neck State Park located on a peninsula between the Chesapeake Bay and the Elk River combines colorful forests with sandy beaches for great viewing. From the Turkey Point parking lot off Route 272 South, it's an easy one-mile walk to the historic 1833 Turkey Point Lighthouse atop a 100-foot bluff at the southern tip of the Elk Neck Peninsula. Climb 35 feet to its top for a spectacular view of the Bay waters and brilliant fall foliage.
• Patapsco Valley State Park, covering 32 miles of the Patapsco River in Howard County, offers great fall foliage views from the comfort of your car if that's a better fit for you. Drive to Valley Overlook in the Hollofield area right off Route 40. From there you can venture into Ellicott City's Main Street, which has shops and restaurants open even as it recovers from fatal August floods.
• In the heart of Baltimore County's horse country, Oregon Ridge Park near Cockeysville has hiking trails that showcase a tree-scape of yellow, orange and red.
• Swallow Falls State Park in Garrett County is located nine miles north of Oakland and contains part of the Youghiogheny River, which flows along the park's borders, passing through shaded rocky gorges and creating rippling rapids, and Muddy Creek Falls, a 53-foot waterfall. The 1 1/4 mile trail through Swallow Falls guides hikers to Western Maryland's breath-taking scenery.
• Other areas to visit close to the Baltimore-Washington metro area: Gwynnbrook Wildlife Management Area in Owings Mills, Baltimore County; Sugar Loaf Mountain Natural Resource Area in southern Frederick County; Seneca Creek State Park just southwest of Gaithersburg; and Dierssen Wildlife Management Area situated between the C&O Canal and the Potomac River in Montgomery County, offering first-rate opportunities for waterfowl watching and quiet interludes for strollers along the Canal Tow Path.

And The Foliage Network posts regular updates on when leaves start to drop and the colors start to turn.

You probably remember from science class that the color change all starts with photosynthesis. Leaves constantly churn out chlorophyll — a key component in a plant’s ability to turn sunlight into the glucose it needs to stay healthy — from spring through early fall. Those cells saturate the leaves, making them appear green to the human eye.

But leaves aren’t green at all. Autumn is the time for leaves’ big reveal: their true color, unveiled as chlorophyll production grinds to a halt. The colors in fall’s breathtaking tapestry are influenced by other compounds, according to the national park’s website.

For example, beta-carotenes reflect the yellow and red light from the sun and give leaves an orange hue. The production of anthocyanin, which gives leaves their vivid red color, ramps up in the fall, protecting and prolonging the leaf’s life on a tree throughout autumn.

And those yellows that make you feel as if you’re walking in a ray of sunshine?

They’re produced by flavonol, which is part of the flavonoid protein family. It’s always present in leaves, but doesn’t show itself until chlorophyll production begins to slow.
