Whether using binoculars, a small telescope or the naked-eye, the Heavens-Above
website can help you to find your way around the night-time sky. In addition to detailed
sky charts, their website will help you find planets, asteriods, comets, satellites and their tracks across the sky.
To give accurate results, Heavens-Above requires the latitude and longitude of your location. As a starting point, when we link to Heavens-Above,
we pass this GPS location for Burholme:
40.061222, -75.083229
Once you're on the Heavens-Above website, you can improve its accuracy by giving a more precise longitude and latitude as your actual position.
We enjoy finding new spots for bird watching and we use the eBird website for local sighting reports and to help identify hotspots.
The eBird website is organized on a county-by-county basis. We have selected Philadelphia County as the starting point when you click on the link below:
As we travel, we always see a community with a name that gives pause. While there are names which are interesting or familiar, some catch our attention or strike our fancy. We always wonder about such a name. If time permits and the community is not too far, we'll usually try to make a side-trip.
Blue Grass (2 miles [3.2 km] to the east)
Note: The GPS coordinates that we are using for Blue Grass have been provided by the GNIS.<1> The coordinates still need to be verified.
We spend a lot of time looking through Gazetteers & Almanacs that were published in the late 1800's and early 1900's. Many of the Gazetteers include the distance from a community such as Burholme to various places of note, such as the White House.
With a nod to our favorite Gazetteers, the straight-line distance<4> beginning in Burholme and extending to:
Harrisburg, which is the State Capital of Pennsylvania, lies 96 miles [154.5 km]<4> to the west (W). If you could drive a straight line from Burholme to Harrisburg, with an average speed<5>of 63 miles [101.4 km] per hour, it would take less than two hours to make the trip. A comfortable walk of 2.2 miles [3.5 km] per hour would take 6 days. A horse and buggy averaging 3.2 miles [5.1 km] per hour would take three full days.
The White House (Washington, DC) is 131 miles [210.8 km] to the southwest (SW). Driving would take less than three hours, a buggy would take 6 days and walking would take 8 days.
The shortest distance<6> to Jerusalem (specifically the Temple Mount and the Dome of the Rock) is 5,766 miles [9,279.5 km] and it lies to the northeast (NE).<7>
The distance to the Great Mosque of Mecca (specifically the Ka'bah - or Kaaba ) is 6,471 miles [10,414.1 km] and it lies to the east northeast (ENE).<8>
The distance to Saint Peter's Basilica (The Vatican) is 4,348 miles [6,997.4 km] and it lies to the east northeast (ENE).<9>

The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required.

An 'estimated' location is one where we have been given GPS coordinates, but are unable to verify the accuracy of those coordinates. That said, we have some confidence that we have placed the marker near the actual location. A typical reason for being unable to verify a location is that it might be on private property or maybe historic and gone without an obvious trace.

Our distances are not driving distances, but are calculated as a 'straight-line' distance. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Burholme) to Point B.Our distance measurements begin at a specific point in Burholme. The point we use is located at these GPS coordinates - Latitude: 40.0612, Longitude: -75.0832 In this case, the coordinates for Burholme have been provided by the Geographic Names Information System (GNIS).

While we have tried to pick reasonable speeds, the rate of travel is very theoretical - obstacles like fences, hills, lakes, river crossings and rest stops have been ignored. When we say 'Days' of travel, we're assuming 8 hours of travel per day.

The shortest line can be visualized by stretching a string on a Globe from Point A to Point B - this is known as a Great Circle Route. Where you might expect the shortest route from Burholme to the Middle East to be East and South, the Great Circle Route actually lies to the North and East.
