trail). The trail and parkway system, part of the Grand Rounds National Scenic Byway, connects with Bde Maka Ska on the north end of Lake Harriet, via William Berry Parkway, and with the Minnehaha Creek trail system at the southeast side of the lake. The bandshell is used for concerts throughout the summer months. The bandshell complex also contains a picnic area and a seasonal outdoor restaurant, Bread & Pickle. A preserved section of the Como-Harriet Streetcar Line runs between Bde Maka Ska and the Lake Harriet bandshell area. Other features The lake is in a direct line with two of the main runways at the Minneapolis–Saint Paul International Airport, and airplanes frequently fly over the area. On the walking path near where Queen Avenue meets the perimeter drive around the lake, there is an "elf house" carved into the base of an ash tree. For several years, one could leave a letter for the elf supposedly living there and find a letter in reply sometime in the next few days. During the winter, the elf door is shut, and a plank appears stating he has "moved to his castle in the east." It reopens in the spring. Other parkland near the lake includes a picnic ground just north of the bandshell, Lyndale Park, and the Thomas Sadler Roberts Bird Sanctuary on the northeast side of the lake. Lakewood Cemetery is located between the southeast side of Bde Maka Ska and the north shoreline of Lake Harriet. Two blocks west of the lake is the shopping district of Linden Hills, often referred to as "a small town in the city". It was discovered on Google Earth that the silhouette of a twin-engine aircraft can be seen in the water. Most have dismissed this as the shadow of a plane flying over, but an investigation was opened into the matter. Further information has determined that there is no sunken plane but rather it is a photographic anomaly of a plane passing over that, due to the exposure, makes it appear to be under the water. Fish The lake contains black crappie, bluegill, golden shiner, green sunfish, hybrid sunfish, largemouth bass, muskellunge, northern pike, pumpkinseed, walleye, white sucker, yellow bullhead, and yellow perch. Some guideline restrictions have been placed on the consumption of bluegill, carp, crappie, largemouth bass, northern pike, walleye, white sucker, and yellow perch from the lake, because of contamination
