Rachel Carson Greenway Trail: Mountain Laurel


Mountain Laurel is blooming along the Rachel Carson Greenway Trail right now. With temperatures expected in the 90's this week, the flowers will most likely be in peak bloom this week. I personally would rank the blooming of the mountain laurel amongst my top 10 favorite natural phenomena. Get out there and see these fantastic plants while you can!

Climate March 2017












My friend Pete and I went down to Washington D.C. for the climate march yesterday. Here are a few photos of the day's march...

Fantastic Spring

Trees are leafing out

Some wildflowers are going to seed, other new ones are beginning to peak.


Forest changes week to week. Last week these flowers were in peak bloom.

I would expect to see something like this along the coast in California, not along the Potomac.

No bells
We've been having a fantastic spring around the D.C. area this year, with many bright days. The forest is in rapid change mode, the sights change week to week and will continue to do so until the fall. Flowers that were once here a week or two ago disappear and new ones arrive...

Diamond Days

Potomac River, high and muddy







Springtime in the Washington D.C. area is pretty special. It can be hard to withstand the cold and grey days of winter. Suddenly though, the temperatures begin to rise, the sunlight starts to intensify. Before long, we are gifted with spectacular crisp, bright blue days. Sometimes it seems we receive only a handful of them before the heavy humidity and heat of summer arrives.

Yesterday was one of those "diamond days," temperatures in the upper 70's and bright blue sky. To any wildflower lovers out there, now is a great time to walk along the Potomac as all the flowers budding right now are either in full display or just beginning to bud...

We Have Some Good News On The California Drought. Take A Look (New York Times)

Here's an interesting article that appeared this week in the New York Times about California's drought situation and incredible snow pack this winter with photos comparing 2017 to 2015...

Spring Has Arrived


Potomac River






I think it's safe to say Spring has arrived this week after being put on hold for a while. Leaves are just starting to bud on some trees around the area and many types of wildflowers are popping along the Potomac River...

California Deserts in "Super Bloom" Thanks To A Wet Winter (NPR)


California Deserts are in a "Super Bloom" according to NPR today. When I lived in LA several years ago, I had the privilege to visit Anza Borrego two springs in a row during peak wildflower season, an experience I will never forget and would recommend to anyone. The abundance of colors, the silence, and the intensity of the light created a powerful experience...

First (and Last?) Snow of 2016/17 Winter

One week before spring, we received the first measurable snowfall of the 2016/17 winter on Tuesday. A slushy, icy, mix of just a couple of inches. Enough to close schools, and thinly carpet the woods...

Gold Mining in Montgomery County Maryland

Random quartz rocks along trail

I follow the littering of quarts pieces up the hillside.

More chunks and flakes of quartz litter the ground as I continue further up the hill

Suddenly there appears several rusted pieces of equipment and manmade trenches and pits now filled and covered with leaves.

Quartz and earthen pits and mounds

I think this could be the spot of the collapsed mine shaft now filled with leaves.

The invasive lesser celandine already popping up on the forest floor after an incredibly warm week where temperatures were in the upper 70's here in Maryland for several days.
I've been doing a lot of exploring around Great Falls and along the Potomac River this winter, mostly measuring trees. One of the surprises during my wanderings was learning that gold mining used to take place in Maryland. Gold Mining took place near Great Falls pretty much right after the Civil War until around 1950 or so. Supposedly, only about 5,000 ounces of gold have been recorded by the U. S. Mint as having come from Maryland (Montgomery County) in that time. Near Great Falls,  miners went as far as 300 feet down and blasted, picked and chiseled away at rock to get the gold out. Tons of stone was sent to the surface to be crushed in mills. The crushed ore was mixed with mercury to draw the gold from the powdered stone.

I was reminded of a hike I took several months ago in my neighborhood woods where I grew up, several miles away from Great Falls and the Potomac River: Many times during past hikes over the years, the trail in my neighborhood woods passes a certain spot where there are quartz fragments littered about. I always noticed them, but never thought much about it. Several months ago, I passed the same spot again and decided to investigate. I followed the quartz fragments up the hillside and eventually discovered several earthen mounds and trenches that were clearly man made, but had been reclaimed by the forest. Pieces of quartz littered the ground. There were rusted pieces of metal in the mounds as well. At the time, I assumed maybe it was somebody's old landfill or something.

It wasn't until a few weeks ago when I read a sign near one of the abandoned gold mines near Great Falls, when the pieces of the puzzle came together. The old miners extracted the gold from pieces of quartz. The round, sunken earth pits were mine shafts, and the trenches were dug for optimum water flow off the hillside. If I had to guess, the gold mine in my neighborhood woods was probably one of the later mines from the 1940's or 50's.

Calvert Cliffs: Chesapeake Bay








It's been over 15 years since I last visited Calvert Cliffs along the Chesapeake Bay. It's amazing how much I didn't remember about the place. I didn't remember the crowds, the 1.8 mile hike to the beach, the large parking area, the playground equipment, the small beach, the offshore natural gas shipping terminal.

We've had a beautiful, warm, President's Day weekend. I visited Calvert Cliffs on Saturday. I guess due to the nice weather, lots of other folks also decided to visit. Temperatures were probably near 70 degrees, much cooler and windier along the beach. I like to do a lot of my hiking and exploring alone, and I wouldn't recommend this hike if you are looking for some solitude, unless you explore some of the side trails. This is a great hike for families, couples, and groups of friends. I was disappointed how small the beach was, the cliffs fenced off to the public. Basically everyone gets herded into an area smaller than a football field. One of the highlights is searching for fossils and sharks teeth which date from the Miocene Period. While the Miocene ranged from 24.6 to 5.1 million years ago, most of the fossils found at Calvert Cliffs date from eight to 11 million years ago. Last time I was here, I remember finding several sharks teeth. Not this time unfortunately.

Overall, I think Calvert Ciffs is worth the visit, just keep in mind that you will be sharing it with lots of other people. The 1.8 mile hike to the beach was flat and easy...
