Illustrated by Matthew Moran and Suzannah Moran

The mid-Atlantic area of Maryland, Delaware, and Washington, D.C. is known many things, such as being the First State (Delaware), home to our nation’s capital or the birthplace of our national anthem (Maryland), but it is also the home of some incredible geologic features. From the Chesapeake Bay to Assateague Island National Seashore to Catoctin Mountain Park, readers will learn about a diverse array of rocks and landforms assembled during more than 1 billion years of geologic history.
From the sandstone ridges and shale and limestone valleys of western Maryland to the sand dunes and tidal estuaries on Delaware’s coast, Roadside Geology of Maryland, Delaware, and Washington, D.C., steers you to some of the best geologic features found inside and outside the Beltway. Thirty-five road guides discuss the landforms and rocks visible from a car window, along bike paths, and at nearby waysides and parks, including Chesapeake & Ohio Canal National Historic Park, Assateague Island National Seashore, Rock Creek Park, and Cape Henlopen State Park. With this book as your guide, find out how the sixth largest impact crater on earth helped shape Chesapeake Bay; discover what moved the rocks at Devils Racecourse in Catoctin Mountain Park; and learn how early settlers put the geology to work, locating major ports where deep tidal rivers issued from mill-friendly, rocky streams.

Your laptop just got an upgrade
Set name: Dual HDMI Adapter
Switched from a desktop to a laptop for work and missed my dual monitor setup badly. This device fixed that. Easy software install, works exactly as advertised. 10/10 if you need multi-monitor support on a laptop.

Must for laptop users
Set name: Space Gray
I’ve been using this hub with my MacBook Pro, and it’s been a game changer. It has all the ports I need in one compact device, which makes it incredibly convenient whether I’m working at my desk or on the go. Everything connects smoothly and performs reliably with no lag, no hassle. I connect second monitors mainly as well as external keyboards and mice. The size is perfect too, it’s small enough to toss in a bag or even a pocket without adding annoying bulk. If you’re looking for a simple, efficient way to expand your MacBook’s connectivity, this hub does exactly what you want without overcomplicating things. So far the durability seems excellent as I have dropped it off the desk several times.

It does what it's supposed to do, except give fluid full screen video.
Set name: Dual HDMI Adapter
It works on a MacBook Neo, but temper your expectations. If you watch a YouTube video with the 3rd screen (and probably 4th screen as well), it's not as fluid as watching it on a 2nd monitor connected to back USB-C port (or via the Neo's internal monitor). This device and the USB-C 2.0 bus are simply not capable of giving you that kind of performance. Also, will need to download and install the driver from the manufacturer's website and allow 2 different permissions for screensharing and to use an updated drive in System Settings.
