Interesting benchmark! Found while on a field trip to DC.

Logging some benchmarks after a long time on my list. Sorry for the late logging.

Eine interessante Variante von Geocaching, die ich so bisher noch nicht kannte. Und wenn man schon mal über den großen Teich gereist ist, muss man dies natürlich auch mal testen! Der Benchmark befindet sich wie angegeben in gutem Zustand am bekannten Ort!! Vielen Dank fürs Zeigen!!

Used to live right up the road from here and walk here almost daily.

Found it with my dad (Dukemartin) and my mom.

Could not get close due to construction.

Found it while visiting DC with our son's class

We came here from Switzerland for vacation. With our rentcar we want to see the East of USA. Two years ago we made a road trip in the West of USA and liked it very much. So now we would like to travel through Eastern USA.

In 20 days we drive from Boston MA to Portsmouth ME, Manchester NH, Green Mountains VT, Troy NY, Niagara Falls NY, Hamilton Canada, Detroit MI, Michigan City IN, Chicago IL, Milwaukee WI, Indianapolis IN, Cincinnati OH, Charleston WV, Washington DC, Dover RI, Atlantic City NJ, Connecticut, Rhode Island and back to Boston MA.

We could see many nice sites and of course we did some geocaching. This benchmark was one of our finds.
During our road tour we found many beautiful and cool caches and benchmarkes. We also met ticks, insects, different wild animals, nice plants and a lot of natural things we didn't know before our trip.
We liked most of the caches and were happy to find so many different boxes and logs.

When we went geocaching it sometimes was sunny and hot and another time it was rainy and cold. So we experienced different weather in different landscapes.

Thank you for this cache. It was great to search and find it.
Greetings from MarSon from Switzerland.

Found it.

was here severalmonths ago and deciced to look for this step and found it!

This is an "unmarked point," so there is nothing to see here except a marble step at the National Academy's building.

If you're here as a tourist, be sure to visit the Lincoln and Vietnam Memorials across the street, and don't forget to say hello to Mr. Einstein at his statue (see photo). This year is the 100th anniversary of the publication of several key Einstein papers -- 1905 was his so-called "genius year" -- and you can learn more at the official website of the World Year of Physics http://www.physics2005.org/

This weekend cache run put 1,502 more miles on the geocaching vehicle. We only found around 44 caches, but we got to add a few more states to our list of cache finds! This benchmark was easy to spot while on our cache run.

Found, but not as described. The NAS building is located between 21st and 22nd Streets, not 22nd and 23rd as per the description. According to the NAS website, the NAS has occupied this building since 1924. Thus, the 1926 description has the building on the wrong block.
